I agree that the ability to have dynamic avatars is a plus but many systems don't allow non-images as URLs for avatars to prevent abuse (though it seems that yours actually is an image so it's not subject to those restrictions). Additionally, there are benefits to having the avatar uploaded individually as well - should your host be unavailable, you don't lose your avatar. Plus, unless you're using a generic image name, like avatar.png, chances are you'll have to update your link on multiple forums anyway. Regardless, I agree that there is benefit to using a link if it's handled correctly so there's pros and cons for both sides.
