Interesting. There is $wgTmpDirectory, but wfTempDir ignores it. Instead of trying to track this down further, go to your includes/GlobalFunctions.php and replace the body of wfTempDir with: function wfTempDir { global $wfTmpDirectory; return $wfTmpDirectory; }

I'll investigate why wfTempDir ignores this. I'm sure there is a good reason, I just don't know it.
