..NET has both JPEG and GIF, although not complete implementations of either.
The .NET GIF always uses 256 colors, for example, and you have to "hijack" a
palette to get specific colors. :-)

TIFF uses LZW, as does GIF

For more info on image compression, you can also look here.

Thats a good idea, but what we need to get at is more related to the
compression method than the file format.

Were trying to detect if the file is of CCITT group 3, CCITT group 4, or
JPEG compression
