Hi there,
I just knocked up a quick hack to use water marking for coppermine. Check it out here: http://www.jvcam.co.uk/coppermine/
It doesn't alter any image on the server, just overlays the image every time a fullsize or normal image is requested (on-the-fly). It uses the 'composite' function of imagemagick but i think you can use a few of the others too to do the same thing. I'm no imagemagick expert.
The watermark image itself is a PNG file created in photoshop with alpha-layer transparency, you can find the one i use here: http://www.jvcam.co.uk/coppermine/watermark.png
If anyone's interested in the code, I'll try tidy it up and make it work for other people too.
I'm guessing that configuration could be put into coppermine to specify where the watermark is placed etc.
Before I tidy up the code, the imagemagick command I use is:
composite -compose over -gravity Southeast '".realpath("./watermark.png")."' '/home/users/jonny/www.jvcam.co.uk/html/coppermine/albums/$p' jpg:-
Obviously that's somewhat specific to my server cos I've not used any of the config includes from coppermine yet.
Anyways, enjoy :)
[edit]
It uses the full path of the image to pass to wm.php to get the image, but really this should use the db pid of the picture else it's not exactly secure.. but this is just a quick hack, i'll change it before i post the code ;)

That would be great! Excellent work.

Who isn't interested in watermarking tool? I am!! I tried this another php based watermark tool... but i couldn't make it work! :cry:
Only works with imagemagic???

ok here it is, it'll probably need some fixes. I've listed the known issues at the bottom:
Step 1. includes/functions.inc.php
Find this line right at the bottom of the script:
return $url_prefix[$pic_row['url_prefix']]. path2url($pic_row['filepath']. $pic_prefix[$mode]. $pic_row['filename']);
And change it to this:
if((($mode == "normal") || ($mode == 'fullsize')) && ($CONFIG['thumb_method']=='im')){
// return the url to the wm script
return "wm.php?pid=".$pic_row["pid"]."&mode=".$mode;
}else{
// it's a thumb, don't bother wm'ing
return $url_prefix[$pic_row['url_prefix']]. path2url($pic_row['filepath']. $pic_prefix[$mode]. $pic_row['filename']);
}
Step 2. Create a new file in the coppermine root dir called wm.php:
<?
define('IN_COPPERMINE', true);
require('include/init.inc.php');
header('Content-Type: image/jpeg');
header('Content-Disposition: inline; filename=file.jpg');
$pid = $_REQUEST["pid"];
$mode = $_REQUEST["mode"];
$sql = "SELECT * FROM ".$CONFIG['TABLE_PREFIX']."pictures WHERE pid=$pid";
$db = mysql_connect($CONFIG['dbserver'], $CONFIG['dbuser'], $CONFIG['dbpass']);
mysql_select_db($CONFIG['dbname'], $db);
$result = mysql_query($sql, $db);
$row = mysql_fetch_array($result);
$pic_prefix = array(
'thumb' => $CONFIG['thumb_pfx'],
'normal' => $CONFIG['normal_pfx'],
'fullsize' => ''
);
$cmd = "{$CONFIG['impath']}composite -compose over -gravity Southeast \"".realpath("./watermark.png")."\" \"".realpath('./'.$CONFIG["fullpath"].$row["filepath"].$pic_prefix[$mode].$row["filename"])."\" jpg:-";
passthru ($cmd, $output);
echo $output;
?>
Make sure you watch those line breaks when copying & pasting as it seems to have broken up some of them cos of page width etc.
Step 3. Get a copy of watermark.png
Get my one from here:
http://www.jvcam.co.uk/coppermine/watermark.png
And put it in your root coppermine directory.
Known Issues
1. Images stored on other servers, I've not even looked at how coppermine handles this but I know it does from looking at the code, but this doesn't support that and I'm not sure it would be possible for imagemagick to do it anyway with remote images.. Thinking it would take some php code to retrieve the image, wm it and then display it - I guess it's possible.
2. GD. GD implementation I've not even looked at yet, I don't know if it's possible but I'll try have a look in the next couple of days and see if it's possible. That said, if you're using GD, then it shouldn't effect the way you use coppermine, it just won't watermark the images.
3. At present there's no way to turn it on or off through the config screen, this is something the other dev's can do easily I'm sure, I didn't get stuck into the config stuff. The only way you can turn it off is to remove the altered script lines. Also, it watermarks both 'normal' and 'fullsize' images, there's no option to turn either one on/off yet.
4. Versions. It should work in anything greater than coppermine 1.1, since that's what I tested it with and I checked the 1.2 code and there's no changes in the lines I altered.
5. I'll try and produce a tutorial in creating the watermark images because it's not exactly straight forward and it has to be a png file. I couldn't get transparent gifs to work at all.
6. Server load. I've no idea how much server load it takes to wm an image every time it's requested as I don't have full access to the server I work on... Anyone who does have access and can check, I'd be interested to see how much load it creates.
I corrected it so that it doesn't pass the full url to the wm.php script, it now uses the pid of the image to find it and look it up in the db. This should somewhat stop people from stealing your images by finding the full path but it's not infallable.
I'm sure there's a few other issues too that I'm not aware of so I encourage people to try it out and see what happens and report back to this thread.
Last note, the wm image I use is this one http://www.jvcam.co.uk/coppermine/watermark.png
Those with photoshop can check it out to see how it works.
Good luck!

Thanks, flex!
FYI, moved this to the MOD section..

Using GD is damn easy: http://www.php.net/manual/en/function.imagecopymerge.php
imagecopymerge combines 2 images and you can even setup a X and Y
And rotate it http://www.php.net/manual/en/function.imagerotate.php
-
Yeh I had a look yesterday at GD but my server is playing up saying it's running out of memory when using createimagefromjpeg(), not sure what's up with that. Thought it was my code to start with but I tried switching coppermine to GD 1 or 2 and I get the same probs :\
Getting this error message:
Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 6400 bytes) in /home/users/jonny/www.jvcam.co.uk/html/coppermine/wm2.php on line 26
-
It seems a lot of servers have this problem.
A jpg is converted to a truecolor GD bitmap when imported.
It seems this uses a lot of memmory or is even a bug.
http://www.php.net/manual/en/function.memory-get-usage.php is a new function since php 4.3.2 check if you can use it and trace the allocated memsize for php tha will maybe give a solution.
-
I used phpinfo() to check the memory allocation for PHP, and it's only 8mb. Which I'm guessing is not enough for the images I'm using to test watermarking, 1600 x 1200.
Unfortunately I can't change the amount of memory allocated for PHP as I don't have that kind of access to the server :\
-
well hack yeah that kind of image uses a lot of memory, try to reduce the color use when opening in GD the function is in image functions list of php.net
-
What i realy mentioned with the new memory_get_usage() function is:
echo memory_get_usage();
createfromjpeg();
echo memory_get_usage();
This way we can trace how much memory is actualy needed for the image.
-
The thing is with the error, is that it's a fatal error message so nothing gets processed after imagecreatefromjpeg. So even trying echo memory_get_usage(); doesn't work :\
Is there an actual fix? Cos I don't see why GD should just fail on a image that size, it's not like it's that massive in terms of digital camera photos.
-
Hi there..
i was trying to add the watermark hack but when it wants to open the pic in full size (so not the thumpnail) i get a X (image not found).
and i dont have any iedea what this could be.
please help..
if you need the files i changed just ask and i mail
-
If you could email me your changed files then I can have a look, email them to jonny (at) jvcam (dot) co (dot) uk
I'll check them and see what's up with them. It could be possible that your installation of imagemagick on your server doesn't have the 'composite' command installed, but I don't think this is likely.
I await your email :)
-
hi
i use the watermark-hack from "DJ AXION".... it's great!

it is possible couse i run it at my own server. sow also i can check what the cpu load will be and memory load but it has to working first..
i will mail it today to you
-
Can you send me the link to your gallery too? I had a quick look at the code, doesn't seem to be anything wrong with it, but I can check the errors if I can see your gallery.
-
ok all fixed up for working in windows as well now. Imagemagick in windows didn't like using single quotes around the filenames, changed them to double quotes.
Thanks to terrorhawk for letting me test on his server & helping me fix it!
I updated the source on my previous post to reflect.

OK, I installed the hack and here's what I got:
Fatal error: Call to undefined function: get_pic_url() in /home/sites/site72/web/coppermine/index.php on line 462
:?
-
Forget it... I used DJ Axion hack, and it runs OK.
The only problem I have is that I want to allow people to download the pics. And when you click right and click "save as", "logo.htm" is in the name field. I would like something like "file" or "image", just like in your hack. An idea about what I have to do?
-
Sorry I've not looked at DJ Axion's hack, so I don't know how you'd go about changing that - probably one to ask him!

I havent tried it, but I think if you change the name of the .php file and the .png file to image or file then it should work, also you will have to edit the functions.inc.php in the includes directory.
I have a question about DJ Axion's hack. I cant post there coz that thread is locked. here (http://coppermine.sourceforge.net/oldboard/viewtopic.php?t=961&postdays=0&postorder=asc&highlight=watermark&start=15) is the link to that hack.
Is it possible to add the logo in the pics that will be uploaded in the future? I have around 800 images in my gallery and I used to paste my logo on then using photoshop (silly me, didnt think of the watermark thingy :P ) Now if I add the logo to all the images then, it wont look good on already uploaded pix.
I will be happy if this is possible.
I am using coppermine 1.1D with a phpnuke portal (v 7.0)
Thanx a lot

When i install the watermark hack for image magick,
the images wont show.
without the watermark if i right click the image and select properties it says the location is: http://home.fjas.dk/gallery/albums/wpw-99/IMGP0141.JPG
but with the watermark it says it's: http://home.fjas.dk/gallery/wm.php?pid=154&mode=fullsize
and i doesnt show any image, only the IE red cross.
i copy pasted the code directly from this thread (and yes i made the line breaks right :D )
any ideas?
-
I think u have changed the name of the file to wm.php try renaming it to logo.php
Also if u want to change the name of the file then change it in functions.inc.php too.
Can someone answer my question too :(
thanx

The watermark image itself is a PNG file created in photoshop with alpha-layer transparency
Hey all,
Anybody point me to a link about creating said "alpha-layer transparency"? My photoshop skills are rudimentary and the googling I did seemed to say that png didn't have an alpha layer?
Pls Help
thx

Just save as PNG instead of TIFF.

Hi!
How can add a watermark for each user a have using gallery? Is it possible?
-
does any of you had problems configuring Image Magick to read gif's - it just doent accepts them!
-

there's a legal issue with gifs, that's why they're not supported. Even if you get them to work, you'll have very large file sizes because the lzw compression can't be used (copyright issue). To find out more, search this board, or better still: go to the ImageMagick site!

P.S. this thread deals with Watermarking, not server setup. Do not hijack other people's threads! :evil:

I get some photos not showing as well... it seems as if it loses them at times depending on how you move around.

ok here it is, it'll probably need some fixes. I've listed the known issues at the bottom:
Step 1. includes/functions.inc.php

And change it to this:
if((($mode == "normal") || ($mode == 'fullsize')) && ($CONFIG['thumb_method']=='im')){
// return the url to the wm script
return "wm.php?pid=".$pic_row["pid"]."&mode=".$mode;
}else{
// it's a thumb, don't bother wm'ing
return $url_prefix[$pic_row['url_prefix']]. path2url($pic_row['filepath']. $pic_prefix[$mode]. $pic_row['filename']);
}
Step 2. Create a new file in the coppermine root dir called wm.php:

Worked like a champ. I don't know sheit about this and it was smooth as silk. I didn't know what the hell the alpha channel was for the watermark, but I figured it out in PS. Hust create the watermark and click on new channel at the bottom of the channels app. No sweat...

hello,
mod is working fine !!
thanks for your work!
greetings fool
-
Got it to work great for me! Thanks for the hack! :D
-
Great working mod. in my case I would like to have my webaddress as a watermark in the thumbnails too. I tried to modify your mod by calling a new wmt.php especially for the thumbnails. This resulted in watermarked thumbnails indeed, except for the thumbnails in the albumlist. These thumbnails didn't show up because $pic_row["pid"] was empty in these cases.
As a workaround I changed the last bit of your code to:
}else{
// it's a thumb, don't bother wm'ing
if ($pic_row["pid"] == ""){
return $url_prefix[$pic_row['url_prefix']]. path2url($pic_row['filepath']. $pic_prefix[$mode]. $pic_row['filename']);
}else{
return "wmt.php?pid=".$pic_row["pid"]."&mode=".$mode;
}
Although this works, part of the thumnails still don't contain the watermark. As I'm no php expert can someone please help me out?
Thanks!,
Pieter
PS I also was wondering if the watermark could be scaled to the picture as well so it's not too big on small pictures and too small on big pictures.

Seeing lots of people reading my post, but not reponding, I presume it's either too hard to do or not interesting enough for most :( .
So maybe someone could tell me how the watermark code could be used to add the watermark when creating thumnail and intermediate pictures on the server. :idea: In that case even linking to the real file on the server (without coppermine) would display the watermarked picture!!!
To prevent users finding the original (fullsize) picture it would also be nice if the original could be prefixed on upload with some prefix that is not too obvious (i.e. fullpref_) or by moving it to another (sub)directory. Any idea's?
Thanks,
Pieter

Hello guys... I would like to move the watermark around and find out where I want to place it. The bottom right is okay, but a little crop and it's gone. I would like to have it in the middle and centered or someplace else. Can you tell me where and how to move the placement of the watermark around the page?
I found one of my images cropped and used on another page. :(
Thanks
-
do we need to download the .png file or can we just make our own? the link to the .png file doesn't seem to work...
TIA!

Sorry about that, I'm no longer using Coppermine (developing my own thing) but you can still grab the watermark image from here if you're applying this mod:
http://www.jvcam.co.uk/coppermine/watermark.png
Most people have got this working, and I'm not up to date on the latest developments with coppermine, but I'm sure watermarking will be included as standard eventually. Also, with what I'm developing I've added an extra field to the photos table which specifies whether that image should be watermarked or not. So you have complete control over which images you wish to be watermarked.
As for thumbnails, I didn't see much point in watermarking them since they are tiny and I can't imagine anyone would want to copy the thumbnail.
With regards to placement, the following line is what you need to change:
$cmd = "{$CONFIG['impath']}composite -compose over -gravity Southeast \"".realpath("./watermark.png")."\" \"".realpath('./'.$CONFIG["fullpath"].$row["filepath"].$pic_prefix[$mode].$row["filename"])."\" jpg:-";
The placement is determined by the '-gravity Southeast', you can change this to any of the eight points on a compass (north, northwest etc..) and it'll position the image there.
As for specific placement, you'll have to look into the finer workings of ImageMagick to sort that out...
Flex :)

As for thumbnails, I didn't see much point in watermarking them since they are tiny and I can't imagine anyone would want to copy the thumbnail.
Well, I've two reasons to do so:
1) My watermark is a text with the siteaddress; I use the thumbnails on another site for publicity
2) When you look at the properties of a thumnail, it's far too easy to download the full non watermarked original . . . (just remove the "thumb_" part and load the rest of the url in your browser)
Hope you reconsider to take a look for me (I solved it partly as stated above, but the solution is incomplete).
thanks!,

Well I understand the security point of view, and that has been on my mind since I created the watermark hack. The only way I can see round this is to place the whole album directory outside of the web root so it's impossible to access them via a browser, yet the scripts can still access them to watermark & output them.
Just thinking about this now, I have no idea what effect this would have on the rest of the coppermine code, I'm not entirely sure if it's as simple as setting up your config files/options and changing the location of the albums directory. However, I imagine that it is possible. Also, not all webhosts let you put things outside the web root.
But if you'd like thumbnails watermarked as well, just change this code:
if((($mode == "normal") || ($mode == 'fullsize')) && ($CONFIG['thumb_method']=='im')){
// return the url to the wm script
return "wm.php?pid=".$pic_row["pid"]."&mode=".$mode;
}else{
// it's a thumb, don't bother wm'ing
return $url_prefix[$pic_row['url_prefix']]. path2url($pic_row['filepath']. $pic_prefix[$mode]. $pic_row['filename']);
}
to this:
if($CONFIG['thumb_method']=='im'){
// return the url to the wm script
return "wm.php?pid=".$pic_row["pid"]."&mode=".$mode;
}else{
// ok so we're not using ImageMagick, so can't wm it...
return $url_prefix[$pic_row['url_prefix']]. path2url($pic_row['filepath']. $pic_prefix[$mode]. $pic_row['filename']);
}
I've not tested that, but it should work as it's just taking out a couple of the if clauses. Test it and let me know.
I also looked into the possibility of using seperate watermark images for each of the 'normal', 'thumb' and 'fullsize' images since I think the wm should be scaled for each one of these... Let me know if you'd like me to look into that, shouldn't be difficult to do...
Cheers,
Flex :)

I did a similar change before, but found that sometimes ($pic_row["pid"] == "") and therefore the wm.php didn't give a picture back. I modified the code for thumnails as follows:
if((($mode == "normal") || ($mode == 'fullsize')) && ($CONFIG['thumb_method']=='im')){
// return the url to the wm script
return "wm.php?pid=".$pic_row["pid"]."&mode=".$mode;
}else{
// it's a thumb, if possible do wmt'ing (wmt.php has the same code as wm.php, but calls smaller watermark)
if ($pic_row["pid"] == ""){
$url_thmbnl = $url_prefix[$pic_row['url_prefix']]. path2url($pic_row['filepath']. $pic_prefix[$mode]. $pic_row['filename']);
return $url_thmbnl;
}else{
return "wmt.php?pid=".$pic_row["pid"]."&mode=".$mode;
}
Everyone wanting to use this, please note that my code doesn't check correctly for imagemagick (because I only use imagemagick ;))
Problem remains that in album list the pictures will not be watermarked and the properties still show the filename, so these files can still be downloaded. Here's and example: http://www.comictoys.info/cpg/index.php?cat=2 . Rightcliking gives the properties of these pictures. I know how to prevent rightclicking, but that will only hold off newbies. Now if you click on one of the pictures there, you will see that all other thumbnails ARE watermarked! This is because of the code I listed above.

@comic: if you're the only one uploading to your gallery, why don't you attach the watermark client sided (before upload)? There are some good free programs out there that do this in no time.

Every registered member, is allowed to upload . . . :P
Besides . . . having coppermine do it for me, takes less time
but thanks anyway for trying to help

I don't know why $pic_row["pid"] would ever return an empty string since every photo *should* (and is required by the database structure) to have a unique ID for each photo, pid.
The only reason why I'd think that you wouldn't get a returned watermark image is if the fullsize image has dimensions below what you specify as the intermediate image (which I don't think my script checks for). There are some alterations which I could do to the script to check for this...
Without looking at your gallery I can't say for sure...

I'm afraid it does and saw another script that tried to hide the url of the pictures do a check on the $pic_row["pid"]. That script also returned the real url for a thumbnail when it was empty.

The example I gave in my previous post only contains pictures with 1200x1600 resolution, while intermediate is 500 pixels. If you follow one of the pictures in the albumlist you'll notice the same thumbnail is in the gallery and that at that point the watermark DOES work! So I guess the check is not the solution. . .
Problem remains that in album list the pictures will not be watermarked and the properties still show the filename, so these files can still be downloaded. Here's and example: http://www.comictoys.info/cpg/index.php?cat=2 . Rightcliking gives the properties of these pictures. I know how to prevent rightclicking, but that will only hold off newbies. Now if you click on one of the pictures there, you will see that all other thumbnails ARE watermarked! This is because of the code I listed above.
-
I think I might know what the problem is. I'll download the coppermine source again and take a second look. I'll post back here if/when I find the solution.

any tip on how to create our own watermark text or graphics? via photoshop.
tia!
-
Thanks this hack worked excellent for me
-
hi! i have this problem, cant seem to find my INCLUDES folder on my Harddisk, but its on my WEBSERVER. inside the INCLUDES folder is the functions.php file not the functions.inc.php as stated in the 1st post by FLEX.
please clarify, thanks!
TIA!
-
I'm guessing that depends on what version of coppermine you're using. Anything above version 1.1 i think it'll be called functions.inc.php, but anything before that I don't know...
As for tips on creating the watermark image, it needs to be a png called watermark.png. If you want transparency then you'll need to create an alpha channel layer in photoshop to do this. I think you do this in the layer window, but I can't remember the exact process to do it. Maybe look in the photoshop help for 'alpha channels' or google it?
You can load my watermark (http://www.jvcam.co.uk/coppermine/watermark.png) into photoshop to see how mine looks and go from there?

Ok I've created a generic coppermine watermark for those having trouble creating one in photoshop/paintshop pro and don't want to use the one I posted (obviously).
I'm still looking at the thumbnail watermark problem.. just takes a while for my head to get round the code again.
Here's the generic watermark:
http://www.jvcam.co.uk/coppermine/watermark-cpg.png
You'll need to rename it to watermark.png for it to work with the script.[/php]
-
i have both include and includes in my server. the include folder is where i have functions.inc.php, thats the file i should edit?
-
functions.inc.php is the file u should edit
-
ok, thanks a lot! wish me luck!
-
got this error message :(
Parse error: parse error in /home/ast/public_html/include/functions.inc.php on line 1109
Fatal error: Call to undefined function: get_pic_url() in /home/ast/public_html/index.php on line 462
-
Umm, u did edit the file right? not just replace the contents of it with what the post says?
-
my index.php page is working already, but clicking the normal picutre give my a X.
-
Well, I took this cool little hack a step further. Instead of creating a PNG offline (which was no real problem - it just didn't suit my needs), I wanted to just use plain old text. So I came up with this, which creates a small PNG on the fly. It puts out 2 layers of text - a foreground and a shadow offset by one pixel to the right and down, then mashes it to the requested image, as the original script did.
Just find this in wm.php:
$cmd = "{$CONFIG['impath']}composite -compose over -gravity Southeast \"".realpath("./watermark.png")."\" \"".realpath('./'.$CONFIG["fullpath"].$row["filepath"].$pic_prefix[$mode].$row["filename"])."\" jpg:-";
And replace it with this:
$line1 = "Line One Text Here";
$line2 = "Line Two Text Here";
$home = "/full/path/to/CPG/home/"; #with trailing slash
$im = imagecreate(180,35); #Modify for size of image you wish
$bg = imagecolorallocatealpha($im,255,255,255,127); #sets background color as white & transparent
$textcolor = imagecolorallocate($im,0,0,0); #foreground text color
$textcolor1 = imagecolorallocate($im,255,255,0); #shadow text color
imagestring($im,3,1,1,$line1,$textcolor1);
imagestring($im,3,0,0,$line1,$textcolor);
imagestring($im,5,2,13,$line2,$textcolor1);
imagestring($im,5,1,12,$line2,$textcolor);
imagepng($im,$home."wmark.png");
$cmd = "{$CONFIG['impath']}composite -compose over -gravity Southeast \"".$home."wmark.png\" \"".realpath('./'.$CONFIG["fullpath"].$row["filepath"].$pic_prefix[$mode].$row["filename"])."\" jpg:-";
One caveat - you may need to create the temporary wmark.png file in the root CPG directory with 777 permissions prior to running the script. Just create a zero length file, and the script will create it the first time it runs.
It's in use on my CPG site - http://photos.railfanzone.com (still in development, but almost there...)
Enjoy!

well tried to possition the watermark on the bottom of the pictures so i changed southeast to northwest but din't work at all. it stays at the top left corner. the link is www.djboxny.com/gallery1
-
Northwest would be the top left corner of the picture anyway...
North = top
Northeast = top right
East = right
Southeast = bottom right
South = bottom
Southwest = bottom left
West = left
Northwest = top left

Nice work! I had considered doing something similar but now there's no need! I think this would be a great way of putting watermarking into coppermine since you control it all from the control panel, instead of having to upload images etc.
The one thing I did look at was trying to use different fonts for the text, but I didn't get very far with the GD/Imagemagick functions for this...
-
It is at southeast and still appears at the top left no matter to what i change it too. this is the code i have inplemted
<?
define('IN_COPPERMINE', true);
require('include/init.inc.php');
header('Content-Type: image/jpeg');
header('Content-Disposition: inline; filename=file.jpg');
$pid = $_REQUEST["pid"];
$mode = $_REQUEST["mode"];
$sql = "SELECT * FROM ".$CONFIG['TABLE_PREFIX']."pictures WHERE pid=$pid";
$db = mysql_connect($CONFIG['dbserver'], $CONFIG['dbuser'], $CONFIG['dbpass']);
mysql_select_db($CONFIG['dbname'], $db);
$result = mysql_query($sql, $db);
$row = mysql_fetch_array($result);
$pic_prefix = array(
'thumb' => $CONFIG['thumb_pfx'],
'normal' => $CONFIG['normal_pfx'],
'fullsize' => ''
);
$cmd = "{$CONFIG['impath']}composite -compose over -gravity Southeast \"".realpath("./watermark.png")."\" \"".realpath('./'.$CONFIG["fullpath"].$row["filepath"].$pic_prefix[$mode].$row["filename"])."\" jpg:-";
passthru ($cmd, $output);
echo $output;
?>
is this correct
-
Hmm that's very strange, it all looks ok to me... By default gravity is set to Northwest but I have no idea why it's not working when you set it to Southeast...
Any ideas what version of imagemagick you're using? I guess it could be a bug with an older version...
-
Is it possible to but the logo's in for outside linking ?
I have searched the board but it's not quite clear to me.
I hope this is not seen as spamming and someone can help me out.

Ok you can try editing wm.php to echo the imagemagick command to see if it's constructing it correctly.
<?
define('IN_COPPERMINE', true);
require('include/init.inc.php');
// header('Content-Type: image/jpeg');
// header('Content-Disposition: inline; filename=file.jpg');
$pid = $_REQUEST["pid"];
$mode = $_REQUEST["mode"];
$sql = "SELECT * FROM ".$CONFIG['TABLE_PREFIX']."pictures WHERE pid=$pid";
$db = mysql_connect($CONFIG['dbserver'], $CONFIG['dbuser'], $CONFIG['dbpass']);
mysql_select_db($CONFIG['dbname'], $db);
$result = mysql_query($sql, $db);
$row = mysql_fetch_array($result);
$pic_prefix = array(
'thumb' => $CONFIG['thumb_pfx'],
'normal' => $CONFIG['normal_pfx'],
'fullsize' => ''
);
$cmd = "{$CONFIG['impath']}composite -compose over -gravity Southeast \"".realpath("./watermark.png")."\" \"".realpath('./'.$CONFIG["fullpath"].$row["filepath"].$pic_prefix[$mode].$row["filename"])."\" jpg:-";
echo $cmd;
//passthru ($cmd, $output);
//echo $output;
?>
Try that and then call the image directly on one of your images. I tried looking at your gallery but it seems your having a few account problems with it, so let me know when you've done the above editing and we'll try get this sorted out.
Flex :)

thanks for the tip!
my webhost got hacked by one of its subscriber! sigh! :lol: everything wiped out according to the webhost!

Let us know what hosting company your are with so we don't go to that company and get hacked too :roll:
-
I did all the stuff in the hack but i get X when viewing normal or full sized images, when i launch the wm script by itself with the correct options it just returns a value of 1.
Pleas help thanks

Hi Flex/Gaugau, I love the script, it works beautifully for me. I was just curious about a quick addition.
Is there a way to turn off the watermark if the image was uploaded by a user? Seems like it would just be a simple if-then statement in there but I don't know anything about php or the variables for the users.
I only ask because my brother got upset when he saw my watermark on his pictures.
And another nice feature would be to specify the watermark by which user the picture belongs to. But I don't really care about that for now.
If you don't have time, could you just give me the variable for users in general and I'll fool around with it? Thanks.

Hi hyperion, thanks for the reference. I've actually already looked at that thread before but can't really make out anything. What does $user1, $user2 etc. refer to?
I don't want to implement that code because I would have to go through all of my pictures (almost 900) and individually add the watermark. I tend to batch upload large numbers of pictures at a time as well. If I could just get this code to check and see if the picture was uploaded by a user, that would be great.

I have made some modify for VIDEO-hack.
Find in include/function.inc.php
return $url_prefix[$pic_row['url_prefix']]. path2url($pic_row['filepath']. $pic_prefix[$mode]. $pic_row['filename']);
replace with
if (is_image($pic_row['filename'])) {
if((($mode == "normal") || ($mode == 'fullsize')) && ($CONFIG['thumb_method']=='im')){
// return the url to the wm script
return "wm.php?pid=".$pic_row["pid"]."&mode=".$mode;
}else{
// it's a thumb, don't bother wm'ing
return $url_prefix[$pic_row['url_prefix']]. path2url($pic_row['filepath']. $pic_prefix[$mode]. $pic_row['filename']);
}
} else {
return $url_prefix[$pic_row['url_prefix']]. path2url($pic_row['filepath']. $pic_prefix[$mode]. $pic_row['filename']);
}
That's will ok for VIDEO-hack.
ps:I have test this with video-Full package.

Hi there..
i was trying to add the watermark hack but when it wants to open the pic in full size (so not the thumpnail) i get a X (image not found).
and i dont have any iedea what this could be.
please help..
if you need the files i changed just ask and i mail
Same here and also noticed others have the same problem.. Did you manage to find/fix the problem??
-
This works great! It is just what I needed! Anyone have input on the slideshow view? It makes it load real slow now.
-
great... it's working fine. thank you.
Does anyone knows how to center the wm just in the middle of the image ?
I saw this:
North = top
Northeast = top right
East = right
Southeast = bottom right
South = bottom
Southwest = bottom left
West = left
Northwest = top left
But I would like to have it just in the middle.
thank you.
shutiri.

When a user views a full size image, how would you make the watermark larger?? Fits perfect in intermediate view....
Thanks
-
Ive got the wm.php working 100%, and im also concerned about hotlinking to my images which is currently taking place.
Im on a windows box, so the .htacess doenst help me much. Ive read though all the postings about hotlinking and nothing really takes care of my issue.
Im wondering if the users cgi referer can be checked on the wm.php page, since this is driving all image calls. If the referer is contained in the allow list, allow the watermarking and images to be displayed. If it is not, then display either another image, or a more anoying watermarked image.
Is this possible?
Im not too familure with PHP, but this would be easy to do im ColdFusion.
I also found the following online regarding HTTP_REFERER, but cant get it to work. (again not php expert)
<?php
$referrer = getenv( "HTTP_REFERER" );
$imagedir= "imx/";
$img = $_GET[sid];
$myDomain = "mysticalillusionz";
if (!eregi($myDomain,$referrer)) {
$imagepath = $imagedir . $img;
$imageinfo = getimagesize( $imagepath );
if ($imageinfo[2] == 1) {
$imagetype = "gif" ;
}elseif ($imageinfo[2] == 2) {
$imagetype = "jpeg" ;
}elseif ($imageinfo[2] == 3) {
$imagetype = "png" ;
}else {
header( "HTTP/1.0 404 Not Found" );
exit ;
}
header( "Content-type: image/$imagetype" );
@readfile( $imagepath );
} else {
header( "HTTP/1.0 404 Not Found" );
}
?>Thanks in advance.

Hi ;)
i have tried this hack and works fine!!!
Just a question: someone here knows how to place the watermark in the Border of the image ??
I need to place it just out the image; can i use those settings and option for imagemagick http://www.imagemagick.org/www/ImageMagick.html ?
I think that the option " -geometry" probabily is the right solution... but can i use it with negative value ???
Thx ::)

Anyone have this working properly on 1.3?
-
I hate to ask, but why on earth would you do this per request and not simply watermark the images as they are uploaded, I mean, its not rocket science. Put this hack on a half busy server and you'd kill it.
-
Anyone with a working Watermark MOD for version 1.3 ?
I've tried for days without luck... I just thought my server or something was wrong, - but when I did the same thing on my 1.2.1 Coppermine machine, - everything worked.
So I have a problem getting it to work on version 1.3.1. I've no problem with 1.2.1
any ideas ?
Kim Igel
-
I'm running coppermine 1.3.1 with GD2, and I tried Karri's hack but came out unsucessful. So I've just decided to wait until the next release which is supposed to have a built-in watermarking feature. This will be sweet. When should we expect the next release anyway?
-
the next release which is supposed to have a built-in watermarking feature.
Who told you so? I haven't heard from any dev working on watermarking being part of the coppermine core code.
When should we expect the next release anyway?
Same answer that is being repeated by open source coders of all projects: "It'll be released when it's ready" ;).

Has anyone done the Imagemagick wtermarking 'hack' with Coppermine 1.3.2 ? It worked for me with 1.2.1, - but not since upgrading, - and I've just tried it again with a new installation of 1.3.2... no go...
?
Kim Igel.
-
hmm.... a bit stubborn here, - so I ran through everything a couple of times. It turns out that in the wm.php file, - in the $cmd construction, - on my server, at least, it failed to resolve
realpath("./watermark.png")
$cmd = "{$CONFIG['impath']}composite -compose over -gravity Southeast \"".realpath("./watermark.png")."\" \"".realpath('./'.$CONFIG["fullpath"].$row["filepath"].$pic_prefix[$mode].$row["filename"])."\" jpg:-";
So I hardcoded it to read : (which obviously needs to be changed, - but it's a full path on the server directly)
$cmd = "{$CONFIG['impath']}composite -compose over -gravity Southeast \"/home/e-smith/files/ibays/foto/html/watermark.png\" \"".realpath('./'.$CONFIG["fullpath"].$row["filepath"].$pic_prefix[$mode].$row["filename"])."\" jpg:-";
and it works...
I worked for me, - so it's just a hint to everyone else having problems with this.
Kim Igel.
-
but it only works when my language is set to English.... not 'danish'' which I prefer for this coppermine installation.
Does anyone have an idea why ?
Kim Igel.
-
Does anyone know how to make this script not take effect to other things like Video's and ZIP's? Right now I have a bunch of ZIP's uploaded and they are erroring because of this mod...
-
Regarding the language problem, - someone suggested removing the trailing blank lines in danish.php (in another thread about batch image uploading), - and removing the empty lines made the batch uplad work (now showing the little icons), - and it also makes this Watermark mod work :-) in danish.
-
There has to be a way to modify wm.php to not mess with things that aren't images... I would do it myself but I am not a php person!
Please help? I really need watermarks but also need ZIP's to work!
-
There's already an easy way to determine the file type - media.functions.inc.php. Just include it in wm.php and call the function is_image before the watermarking happens, like this: $whatisit = is_image($filename), where $filename has the path and filename of the file in question. If it returns true it's an image. You could wrap the watermarking code inside an if-then statement:
if ($whatisit)
{
... watermarking code
}
-
:) Thanks
As I was reading your post trying to figure out exactelly what you wanted me to do (me and any language don't get along well) I saw this...
"where $filename has the path and filename of the file in question"
And I didn't quite understand it. Path and filename to which file? The ZIP I can't get working? There are bunches and more would be uploaded by different people...
If someone would be o so kind to post a modded wm.php useing kegobeer's instructions I would love you for the rest of my life :-P
I don't know why but I can totally understand nearelly everything in computers... I just can NOT understand programming languages and 3D proggies... I really need to work at php maybe get myself a book...
-
So ImageMagick, we can't just do a command lime from config menu in Coppermine?
Where can I find a thread about the DJ Axion mod for imagemagick? The links were dead.
Thanks
And does thsi still work with 1.3?
-
all available watermarking mods are within this very sub-board named "Watermarking & image manipulation (http://forum.coppermine-gallery.net/index.php?board=33.0)". Mods that don't appear on this board are simply not there, and have never been.

Well, I just tried this and after reading reports on it not working with the recent ver of coppermine, those were dumbfounded.
I installed it with no modifications and it works perfectly.
You can see it at www.topdrunks.com
-
yes, - it works, - but with a slight delay... I noticed it on my server, - and apparently you have it too :-), - just a small 1 second lag... but still, - it brings up the question of doing this on-the-fly, - or as a batch-job before uploading images.
Kim Igel.
-
Yeah, I noticed the delay.
It would be cool if the script could do the commands during batch add files rather then "on the fly...." I assume it wouldn't be too much to do, but I sure as hell wouldn't know what to do ;)
-
In another thread Gaugau suggested this :
http://www.picture-shark.com
it's free, - and apparently it build for exactly batch-adding watermarks to images... :-)
take a look ...
If your normal work-flow involves sorting the images, - maybe do some adjustment's in Photoshop using batch, - uploading to your server.. then it would be easy to 'plug in' a step along the way that watermarked everyting in a specific folder...
Kim Igel.
