Images and Graphics on the Web
•Graphics Interchange Format (GIF) is an older format for images that does a very good job of compressing small- or medium-sized files. •Most GIF files you find on the Web have a .gif extension and can store only up to 256 different colors. •The GIF format is widely used on the Internet for images that have only a few distinct colors, such as line drawings, cartoons, simple icons, and screen objects. •An animated GIF file combines several images into a single GIF file and gives the appearance of cartoon-like animation.
