Plus, the image is *already* there, but you're still going out of your way 
to piss them off? After they've sat patiently at their computers with their 
dialup connections, you arbitrarily delete their file and make them do it 
again (thereby also consuming more bandwidth)?

The technology exists to solve the problem without ruffling feathers. Use it.
