I decided to "modify" this mod so it'll work in CPG 1.3 and my brother helped me fix the "_normal" bug
Permanent Watermark with GD2 MOD
For CPG users who wants to add GD2 watermark function on their gallery.
This MOD uses GD2!
Here is how to mod CPG 1.3 to be able to add watermark automatically on new pics and by choise on all pics in selected album.
This is quite long post, but it takes only about 10 minutes to add this mod
Files that needs to be modified:
Lang/english.php
include/picmgmt.inc.php
util.php
config.php
(and 4 SQL command to execute)
REMEMBER to take backup from all files that You are modifying
1.
Open file Lang/english.php
Find this:'th_wd' => 'Width',
Add this after it
'wm_bottomright' => 'Bottom right',
'wm_bottomleft' => 'Bottom left',
'wm_topleftt' => 'Up left',
'wm_topright' => 'Up Right',
'wm_both' => 'Both',
'wm_original' => 'Original',
'wm_resized' => 'Resized',
Find this:
array('Display notices in debug mode', 'debug_notice', 1), //cpg1.3.0
Add this after it
'Image watermarking',
array('Watermark Image on upload', 'enable_watermark', 1),
array('Where to place the watermark', 'where_put_watermark', 11),
array('which files to watermark', 'which_files_to_watermark', 12),
array('Which file to use for watermark', 'watermark_file', 0),
Find this: 'delete_orphans' => 'Delete orphaned comments (works on all albums)',
Add this a line after it 'watermarks' => 'Add watermaks',
'watermark_normal' => 'Resized images only',
'watermark_image' => 'Original sized only',
'watermark_both' => 'Original and resized images',
'watermark_wait' => 'Watermarking images...',
'watermark_continue_wait' => 'Continuing to watermarking originals and/or resized images...',

Find this: case 10 :

Few lines below isdie('Invalid action');
Now we need to paste this //Watermark place
case 11 :
form_watermark($element[0], $element[1]);
break;
//Which filest to watermark
case 12 :
form_watermark2($element[0], $element[1]);
break;
case 13 :
// do nothing
break;
default: between them.
After You have done it, it should look like this (I have put couple lines befor and after those lines in this example (hoppe You got it, becouse of My poor english :? // tabbed display fix
case 10 :
form_number_dropdown($element[0], $element[1]);
break;
//Watermark place
case 11 :
form_watermark($element[0], $element[1]);
break;
//Which filest to watermark
case 12 :
form_watermark2($element[0], $element[1]);
break;
case 13 :
// do nothing
break;
default:
die('Invalid action');
} // switch
} else {
form_label($element);
5.
Then You need to execute theese SQL commands with phpMyAdmin or Webmin, etc.
insert into cpg11d_config (name, value) values ('enable_watermark', '1');
insert into cpg11d_config (name, value) values ('where_put_watermark', 'bottomright');
insert into cpg11d_config (name, value) values ('watermark_file', '/your/full/path/to/logo.png');
insert into cpg11d_config (name, value) values ('which_files_to_watermark', 'both');
Thats it. Now You can go to settings and set it up.
Actually You need to go there, before trying to add new pics.
You have to change 'Which file to use for watermark' to point to your own logo.png file that is used as watermark.
This should contain every modification I have made.
