I never installed MediaWiki on Windows, but the Apache may run as none of the 4 users. On Linux, the Apache usually runs as the user of "apache". If you couldn't assign the write permission to "apache" for the "uploads" directory, you could try to grant the writre permission to "everyone" user for the "uploads" directory. Anyway, by default, images are uploaded to the $IP/mediawiki/images directory on Linux. Please also check the permission setup for this directory. Ross
