I have a really really pimp avatar that I want to use, however it's 60x60 (smaller than allowed) but it's 30k size.

yes animated gif.

is it possible to get it raised to that? or will the 20k cause to much bandwidth issues?

 

If we raise it members WILL take this as an opportunity to "upgrade" their avatars, thus resulting in such issues as bandwidth consumption. I don't see the need to raise the avatar specifications at this time.

 

I'd like to see the size upped to 100x100 (or even 100x75 to keep the vertical size down), but the actual file size seems ok.

 

It's the least of our concerns at the moment. The all likely hood of the specifications being upped is slim IMO.
