    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.
