Thread:Project:Support desk/image resize thumbnails on synology diskstation

When I want to include a image as a thumbnail, I get the message that there was an error trying to create it (with nothing more info inside), no matter if I am trying to resize jpg or png. Ok, so I did a lot of research to make sure that I read the fine manual before I ask you.

I assured the following:
 * imagemagick is installed in /volume1/@optware/bin/, there is the 'convert' file
 * I made links with ln -s to this directory in /opt/bin/convert, (usr/bin/convert, /bin/convert
 * I even did chmod 777 on /opt/bin/convert so I assured it doesn't lie on the file rights
 * I entered the following options in my LocalSettings.php:
 * I made /mediawiki/images/temp and /mediawiki/uploads and I chmodded it to 777 to again be sure that it's not the file permissions

I installed libpng, libjpeg and openjpeg via Apache IPKG

I tested the convert-file on the shell and I can convert pics with convert image.jpg -resize

the uploaded images are in /mediawiki/uploads in some random subfolders like '2' or 'd'. They are about 30-50 KB.

I also checked my php.ini if there is set 'disable̠function' but the string is empty, so exec-function in PHP should work. in the folder /mediawiki/uploads, where the images are, there is no .htaccess-file yet Here are the folder's options of my httpd.conf

What else would I possibly have to check? Is there anything I should check in my httpd.conf? TIA
