I'm guessing it's a dithered image, so RLE isn't going to be much use.

As an aside PNG does have good performance on monochrome images, unlike JPG.

I think your best best is to use uncompressed GIF first up, which willthen allow you to implement (GIF) compression at a later stage if you'reever feeling masochistic and/or bored! ;) LZW should do a half-decentjob with dithered monochrome images?!?
