Images are currently not working, since it seems there been corrupted files in the image service. I will probably need to use a backup to get it working again, so some images might be lost.

EDIT: Images from 16/07 16:00 CET to 17/07 13:45 have been lost, but the image service is now working again.

I think I will do more frequent backups to avoid losing too many images, if it happens again.
