Was picture.ppm a digital graphic, or a photo / still ?
There is a major difference in the compression done on computer generated
artwork, and that on a real-life picture ... take a one of the piccies Liam
posted the other day to the ILAP site, versus a computer generated graphic.
On another note, does anyone else recall a Fractal Image Format ... it could
store 10s of MB of JPG files on a floppy, and could zoom in smoothly on
real-life images up to about 10x ... again with digital images performance
