I've just hacked up a program that generates an html parts-list (with pictures) that bears an uncanny resemblance to the one found at Lutz Uhlmann's page ((URL) can also be told to generate a list with used-defined classifications to produce output (...)

(...) This problem is why I chose PNG. It compresses flat shaded images quite well and still retains the true color pixels.

(...) Well, it's not *that* big'o'deal: GIF is restricted to 256 colors. If you convert down to 256 colors, will PNG give compression on par with GIF? If it doesn't, you can always look into BMP/RLE. FYI, here are some links into the MS (...) (24 years ago, 28-Mar-00, to lugnet.cad.dev)
