Of course large GIF images tend to have smaller file sizes because so much
of the original color information is discarded when they are created.  And
of course large PNG images tend to be better in that they reproduce original
images more faithfully than JPEG.  Neither GIF nor PNG, though, is both
smaller and better than JPEG for large screen shots of computer desktops,
modern video games (*NOT* emulated ancient games), or movies--some of the
most common uses for screen shots.  For complex content, JPEG offers a
decent compromise between the two (although personally, I am leaning farther
away from file size concerns toward quality concerns these days).
