MediaWiki seems to use 'convert' from ImageMagick. For ImageMagick you can assign a tmp-dir via MAGICK_TMPDIR (default: '/tmp'). MediaWiki does not set that variable. In shared-hosting situations it would be nice to have MAGICK_TMPDIR configurable. That way each user could have his temp-files in his own space. Currently all goes into /tmp. This can fill up a tmp-partition easily.
Should be pretty easy. Just make a new global (null by default) and then set the environment variable in Setup somewhere of the path is specified by the user.
WORKSFORME. Didn't realize we already did this. See http://www.mediawiki.org/wiki/Manual:$wgImageMagickTempDir
