How come my Brightkite Avatar is blank?

My Brighkite avatar is not showing up on the 'Account' part of the 'Settings' and as the results, all the avatars of my Brightkite friends on my friendstream are blank! I've tried to removed and re-added my Brightkite into my Socialthing several times as well as changed the avatar I use on my Brightkite to no avail. Can somebody please help me? Thanks so much!
