Rather late, but if you're still interested in this avatar then try uploading it to
imageshack.us
They're a free, no registration website and they do pretty good stuff.
Make sure to select the video/movie clip option for this avatar of course.
Edit: Was thinking about this after I had posted it...
shack formats the picture/clip into a forum friendly code, not sure if it'll work on here but it should
Let me know how it works out
