I cannot imagine there is a way if the image is to display in a client at all, the image is
now there, and the client can do anything it wants...

But it should not, if the server sends the image with the appropriate 
"no caching" and/or "expires" HTTP headers.

Now how one would set such headers easily in Tomcat for static 
documents, that I don't know.
But I am sure someone on this list does know.
If that is indeed the issue..
