JPEG AND GIF are the standards for use on the web
In addition to what other people have already mentioned (JPEG is lossy and thus unsuitable for logos and other discrete-tone graphics; GIF is (currently) patent-contaminated and therefore cannot be used with GFDL), I would also like to point out that GIF has a lot of actual technical limitations that, in themselves, already make it not a choice for most application: * Limited to 256 colours * Therefore, in a sense, also lossy. A >256 colour image will need to be reduced in colour depth. This results in dithering or diffusion, which greatly hurts the compression ratio * Only single-colour transparency * gzip compression (which PNG uses) often outperforms the patented LZW compression (which GIF uses)
I really hate GIF. Does it show?
