It is the responsibility of the web designer to ensure that a site will be
viewable under the widest possible range of configurations. The GIF
format actually has a variable colour depth, up to 256. Any photomanipulation
program worth its name - Photoshop or Paint Shop Pro, for example - will
offer web-optimized encoding palettes of 216 colours, with adequate
dithering algorithms that allow even users with lowly old VGA displays to
view graphics correctly. Have you (Mike) tried this?
