Btw, for those interested in fucking with the surfer's ability to easily save images a bit more efficiently, the easiest thing to do is to write a javascript function that accepts a code as input, then outputs the filename based on that. Even just using rot13, it would be sufficient to stop 99% of all surfers. Of course, you still need separate code to stop the right-clicks.
Oh, and don't think for even a second that you'll ever truly stop determined surfers from saving stuff. You merely increase the time it takes them to get it a slight bit, while inevitably breaking some functionality for others.
