Avatar caching is bad

IMHO, at least. I am trying to use a random image CGI (http://members.hostedscripts.com/ran...user=filburt1, which produces random avatars, refresh the page to change this one: http://members.hostedscripts.com/ran...?user=filburt1). But since VBF caches it, it just sticks with one avatar and never changes it. :(

Aww muffin....

surely it's better that it gets them all from the same place, rather than replying upon other servers working
