Fractal compression is very good, and is what Microsoft used for the
photographs on Encarta, although it never really took off in the digital
imaging world. Its downside is that it's a proprietary format and it is
expensive to compress, although decompression is relatively cheap. JPEG OTOH
is about the same for compression/decompression. The coming thing in
digitial image compression is wavelets, and this is the technology on which
the JPEG 2000 standard is based.
