Thought I’d pass along this 30-second hack in case others found it useful. I’m sure there’s a more elegant way of doing this, so feel free to chime in if you can improve it.
In the CBox blog/sites directory, each blog is accompanied by the avatar of the site’s administrator. If there are multiple administrators, it seems to pick … well, I’m not actually sure how it chooses among the administrators, but it picks one.
This works fine for individual member blogs, but less so for collaborative or topic-focused sites. You may find yourself wishing you could use a specific user’s avatar or supply a custom avatar. Here’s some edits to
/wp-content/plugins/bp-custom.php that let you do just that.
