Avatar not changing...

[Mushroom Panda]

I have a NES avatar right now of a mushroom (coloured black/white). I want to change it to (http://i167.photobucket.com/albums/u141/BeardedBugs/shrooms55ot.gif)

But, when I try to change it from the user CP, it changes back to the NES mushroom. What's up with this?

EDIT: Thanks to whoever changed it, and/or if it fixed itself

Your browser was probably caching the avatar. Next time, just try pressing CTRL F5

Thanks. I did clear my private information, and it worked.
