Yes, that is some of what I was looking for. Thing is that it still only shows the standard gravatar, not the uploaded user profile image. That image was uploaded through the BP change avatar dialog on the main site ie. http://site.com and seems not to show up on the users own blog at http://blog.site.com. It does show up when going to the profile using the links in the menu bar though, those links point to the main site domain.
It is a subdomain multiuser setup, but it should still work shouldn’t it?

Allright, I moved it to the wp-content/plugins folder. I can’t see any different in widgets or plugins, but I’m not sure where to look for it.
Just to clarify, I’ve been working with WPMU for a couple of years, it’s just buddypress that’s virgin territory for me.
