I am uncertain whether or not Bugzilla accepts Wikia bug reports, but I was directed here by their site. The bug manifests itself in that SVGs (and at least one PNG) are displayed as a gray box with "Error creating thumbnail: Unable to create destination directory" on it. Other images are displayed as red links, even though they exist on the server—their Image: pages, however, do not: they can be retrieved from the various image version links, but they are not technically "there".
You can take a look at the effects here: http://nationstates.wikia.com/wiki/Adygea
This is almost certainly a problem with missing directories or bad directory permissions on the server. You'll have to check with the wikia server admins.
No other—to my knowledge—Wikia has this problem. Wouldn't it affect everything if it was a root problem (as I guess you're suggesting—?)?
Speaking from experience on our system, it is likely that the individual subdirectory for your wiki is missing/incorrectly permissioned.
