Thanks Gizmo. I did try that, but alas I did end up with enormous avatars. It seems the upload size isn't actually restricted to the right size, so if you turn off the image sizing at the front end it all goes to pot. I see why it was done, now.
It would be nice if UBB made a larger version of the default avatar set, so at least you could have an option or two... *looks hopeful*
Thanks again.
