The Graphics Interchange Format (GIF) is a bitmap image format that was introduced by CompuServe in 1987. GIF defines a protocol intended for the on-line transmission and interchange of raster graphic data in a way that is independent of the hardware used in their creation or display. GIF test suite can be used to test robustness, security and reliability of implementations using GIF.
