June 20, 2009 1:15am OH, and I think you should make this your avatar -- at least for now.
Simply:
1. Click "my stuff" in the black menu bar at the top.
2. Click "Manage Photos"
3. Click "Set as avatar" next to this image (or whatever image you wish to use).
Your image will now show up in profile lists and on your front profile page, etc.
