If you actually downloaded the images, you may have noticed that the image in GIF format takes roughly 4 times as long to download as the image in JPEG format. For this reason, we recommend that scanned photographs be saved in JPEG format.
GIF format is best suited for line drawings and logos.
Another thing you may have noticed if you downloaded the images is that they would approximately fill the viewing area of a web browser or image viewer running in VGA mode, which is a very typical setup for many computers. That is why we recommend scanning photographs at 75 dpi if they are going to be used on the web.
