I changed my logo by setting $wgLogo in LocalSettings.php. I believe that's the right way. It only shows up on some pages. It seems like it likes to show up on editing pages, login pages--pages with forms. It doesn't show up on content pages (when you're only reading them), the main page, etc. When it doesn't show up, I don't see a broken image box or anything, it's just not there. It doesn't seem to matter what skin I use, and I've been sure to clear cache and restart httpd, etc. It's actually happening the same way in two different installations. In both cases the logos are nice and small; one of them is a png with transparency and the other is a non-transparent png. Any ideas? Side note: I'm new to MediaWiki, but I'm having a really hard time googling for help. If I include "MediaWiki" in the search string, the results seem to return every third wiki out there, rather than help about MediaWiki. Any tips there? Thanks, Matt
