I'm thinking about simplifying logo updates by simply using

$wgLogo = $wgUploadPath.'/b/bc/wiki.png';

This way all the users need to do is uploading the image to Image:Wiki. png. The image should probably be protected, but that's up to the sysops.

This might also be a sensible default in DefaultSettings.php, we'd need to supply images/b/bc/Wiki.png in that case.

Any thoughts?
