Re: How do I add a logo?
I did find a couple other options. Not exactly what you mentioned, but they might work for you:
Showing the last image uploaded to the BP Media plugin: https://buddypress.org/community/groups/bp-album/forum/topic/limiting-photos-shown-and-also-how-to-display-latest-uploaded-photo-on-users-profile/
The latest BP Oembed plugin was working to support embedded image in the profile: https://buddypress.org/community/groups/how-to-and-troubleshooting/forum/topic/how-to-allow-user-to-upload-image-with-a-field-in-profile/ Basically, users could put a link to a flickr image (or other oembed enabled site) and the image would appear in their profile.
