The GIF format is easy - implementing nice, face LZW compression is a
little harder :-)

I've always just used a simple RLE compressor I wrote myself years ago
to store Apple II graphics. You could probably implement a TIFF encoder
that used this technique to produce a file readable by most graphics
programs...

If you're going to generate a web-friendly format though, why not
implement PNG instead? It's certainly not been done before on the Apple
II
