JPEG: Small file size, lossy compression, 24 bit color. I think there is 
a new JPEG standard(JPEG 2000?) that features lossless compression, but 
I don't know any programs that use it.
TIFF: No idea, never used it. It doesn't seem very common.
PNG: Lossless compression. File sizes can be a bit large compared to 
JPEG, but small details and colors are preserved. Best if you want 
top-quality images. Not sure about possible bit depths, but I think 
there are 16, 32, and 48 bit versions.

JPEG and PNG are supported by most web browsers, but I don't know about 
TIFF.

Maybe povray.off-topic would have been a better group...
