See the paper: Barnsley M.F. and Sloan A.D., A better way to compress images, Byte, 13, 1, 215-223, 1988. Some months ago, we gave some of our images (640x480, 256 colors) to compress by this method. Compression ratio is very impressive, but for us (in histology), the quality of compressed images was not sufficient. I think you can decompress your images yourself (with a 386 or 486 machine), but compression is slow and needs a very powerful computer or other special equipment. The company that developed this method is called Iterated Systems, Inc.
