I think even 80x80 would be nice.

Often times I want to use a photo of all 4 dogs in my avatar and NOT have it animated. However, reducing it to 60x60 you cant even tell what it is!

I don't really like animated avatars, so maybe if there's an option for larger, NON-animated avatars? I know a lot of boards allow 100x100 but they only allow non-animated avatars.
