Pictures from a digital camera or scanner are generally very large in both file size and dimensions (width and height) and simply not suited for email and web. For instance, unless you were forwarding the image to a printer, there is no need to send high-quality images to friends and family because not only will the process take a longer time and waste internet bandwidth, the entire picture wouldn’t fit on one screen (on most monitors) which results in horizontal and vertical scrolling for the recipient.
