Having looked through the settings for the updated forum, it appears as though the InvisionBoard developers have done away with avatars. Profile photos is what remains, and the CBn team are currently discussing how we want to manage this, or if we want to keep it at all and just use signatures. Or the other way around.
Courtesy of our fearless leader, The Admiral, Apparently, he is pondering getting rid of either sigs or Profile pix. Personally, I say lose the pix.
