    Ok heres the scoop. GIF is a proprietary format. JPEG I think is also a Propretary format. GIF was involved in this controversy by suing someone i dunno who for using it. Thats why the Open Source Community created PNG. GIF Sucks as far as quality goes since its only 256 colors. It however can be animated unlike jpg. JPEG quality can be compressed and it supports 32 bit color. There are some special features like progressive added to the format JPG. Most OS's can handle the old GIF and JPEG. Apples new MAC OS X cant handle GIF or JPEG(i dont remember which one) as far as opening it as a file goes.. But they can handle the format theyve been pressing which is TIFF. PNG has good quality, and it can be compressed so its kinda of better than JPEG. However, MS IE cant handle some of the features of PNG and so as far as webmaster experience goes its best to use JPEG and hope no one has the screwy AOL browser.

    JPG are nice looking and good quality.
    GIF are good for transparent images ^_^

    PNGS take longer to load and AOL sometimes cant view them and they are huge

    Use 8bit PNGs. If you need more than 8bits of color use 24bit PNGs. If the images are too big use JPGs (keep PNG copies of the orignals) as they will artifact the image to make it use less space.

    Use gifs if you need to animate something. Gifs are the best choice until MNG is supported by web browsers (namely IE).

    Btw, with PNGs, stay away from Alpha Transparency until IE has proper native support for it. There are two kinds of transparancy (I forgot the name of the other one) use the one that doesn't have Alpha in its name.

    Most of the time that is because they are using 32bit PNGs on an image with huge dimensions that only needs 8bits.
