Hey, that's very clever. There is specialist software that can reduce image 
file sizes to a minimum. You can
go into each channel and reduce that until you no longer like the look of it, 
and play with it until the right
balance is achieved. One application for this is porn over the web, and I have 
to say I can only admire the
image quality that gets packed into a tiny image size.
