It's working in my profile.
Did you have it up before & it just stopped showing up? If so, did you receive any kind of message about it?
I've re-sized it, so it isn't too large. The only thing I can think to tell you is to make sure the avi space in your user profile is completely clear, then copy & paste the direct link
from the list of image links from my photobucket account for that image (use the link I provided in previous post) to the avi space on your profile page. It worked in my profile.
