Saw your question posted, and I have an answer for you.

TIFF and PCX formats are coded for Print, or CMYK (Cyan, Magenta, Yellow, Black), and JPG and GIF are coded for screen or RGB (Red, Green, Blue).  CMYK is good for print, because it only allows for up to 16+ thousand different colors, the maximum capability that printers today, even professional print presses can do.  RGB is almost limitless, but, allas its in the millions somewhere where the ammount of distiguishable colors it can allow.  JPG and GIF are different though.  While GIF handles solid color, and solid color transitions better than JPG (this is why it does well with animations) and has a smaller file size, JPG handles, on the pixel level, a smoother transition between similar colors, thus the higher file size (usually used for photographs).

As for BMP, it was actully created by microsoft, and never caught on, due to 2 things, its HUGE file size, and its poor image quality, especially with photographs.

Any questions?  Feel free to e-mail me back.  I hope this answered your questions.
