A 60*60 avatar would fit - max. dimensions are 100*100. The image in question may be too big in terms of bytes though.
Let me know the details and I'll see what I can do.
This board does seem somewhat more efficient, thus far, than the last incarnation and bandwidth usage has dropped...
Just reviewing the vB resource forums. Appears bulit in avatar resizing does not happen. Also, every avatar you choose is being uploaded to NSC - think bandwidth-busting.
However, it looks as though there are hacks I can make to allow them to be hosted elsewhere and be resized - give me a while....
