I have been trying for 2 weeks to figure out how to get Mediawiki 1.22.5 to properly handle images: still no real progress; Here is the message I'm getting now. I think these are all related to some permissions issue, but I have tried everything I know of & I have researched the web extensively & tried many 'possible' solutions. Here is the situation: /var/www/ is owned by root:root permissions 0755 /var/www/mywiki is owned by myusername:myusername permissions 0755 /var/www/mywiki/images is owned by myusername:myusername permissions 0777

I am currently running this on Debian linux stable; when I load up a webpage I get a mixed array of images issues: as in some images load and display and others don't.

error message from web page:

Error creating thumbnail: convert.im6: no decode delegate for this image format `/tmp/magick-3PI8Zdf7' @ error/constitute.c/ReadImage/544. convert.im6: no images defined `/var/www/mywiki/images/tmp/transform_4a98a4281d46-1.png' @ error/convert.c/ConvertImageCommand/3044.

error message from Apache2 error.log:
