I am not an expert on this so I am more likely to be wrong than right...
I think you need to use a static html page on a different server. Dont know about Geocities but Yahoo email pages assign dynamic image names so your image name will work that instant only and not later. Or sometimes some sites use special filters to block other sites from accessing images on their site. Could be Geocities is doing that when you refresh the page on the Axiom site.
The right click may be working because of your browser cache I think.
Good luck.
