John, I see what you mean. One other thing you might try is to copy the html code for the full size image to your profile and see if that works any better.
Also copy and paste the full size image code onto one of your posts like I did here. If it works okay, then maybe its just the confines of the 48x48 that's messing it up. If it's still not working right, maybe it's the gif itself that's causing the trouble.
I dunno. Hope Dennis can come along and help. If it can be done, he'll be the one to know how to do it!
