The following errors were encountered and need to be corrected first:
--------------------------------------------------------------------------------
The installer found the ImageMagick 'convert' program in  C:/Inetpub/wwwroot/other/ImageMagick/, however it can't be executed by the script.
You may consider using GD instead of ImageMagick

Full Control permisions for Image Magic & Gallery.


What Shoud I do now??

[Joachim Müller]

you'll have to do the equivalent to chmod in the Windows world: open your windows explorer, right click on the folder that contains ImageMagick's convert.exe, select "properties" - "permissions" and make sure the user the script runs under (usually a user called IUSR_hostname) has read/execute permissions on it.

Ok, I added all availible permisions for IUSR_<pc_name> but it's still not working, i creater user "EVERYONE" with 0777 permisions, (full control) but it's still not working.

[Joachim Müller]

as you installed it on windows, you should be able to run the tests from the ImageMagick package. Do they work?

I've done the same thing, giving the web user IUSR_<pc_name> full control.  Experiencing the same problems.

I'm running Image Magick 6.2.4 on Windows XP Pro SP2 with Coppermine 1.3.3.  Doesn't seem to be a permissions problem from what I can tell.

Then for you the same question applies:

as you installed it on windows, you should be able to run the tests from the ImageMagick package. Do they work?

Don't forget to allow full control for the system as well.

[Suffering]

I don't seem to have any tests to run in my particular ImageMagick installation (6.2.4).

I did however make sure that the SYSTEM user has full control of the ImageMagick directory as well.  It didn't make any difference.

Is there anything else I can do to simulate a php exec to test whether this is a permissions thing or not?

[Joachim Müller]

There definitely are tests that come with ImageMagick, read the docs that come with it. Note that this board is not dedicated to web server setup support, but only for coppermine. We recommend GD anyway.

If your server is running PHP in safe mode, which it is likely to be if you're using a (free) shared host, your scripts don't have the right to execute shell commands. As this script runs ImageMagick as a shell command, you won't be able to use it.

also, imagemagick needs to run exec() function in php pages, which is disabled by most virtual host servers.(php.ini - disable_functions)

You could
a. ask your hosting provider to disable safe mode or
b. use the GD library to generate your images.

ImageMagick is far more powerful than the GD library, but you can use the latter even in safe mode.
