It's best if people do not use copyrighted work for avatars.  However, "fair use" does allow for personal use, and many of us may not even recognize images that aren't your own. I would have never known that your image was Snape.

I'd let your Snape avatar stay, but if we get a copyright complaint I'll need to remove it (and hopefully you'll be understanding about it)  smile

I'd rather not have to monitor avatars daily :)
