As computers and the Internet became more widely used, problems resulted with the use of photos. Photos take up a relatively large amount of computer space and downloading or maneuvering photos around can be time consuming. Be reducing the size of the image, or compressing it, these problems can be solved. One popular such format is called JPEG, which stands for Joint Photographic Experts Group. JPEG is know well-known as a standard photo format and it makes sharing photos between computers much easier and faster.
