GIF free

As of today the Graphics Interchange Format (GIF) is no longer patent-encumbered in the USA. The patent for LZW compression that Unisys owned has expired in the USA, but the patent is still in force in other countries until 2004. Use of the PNG file format instead of GIF is still recommended for static images. It offers superior compression, better image quality, and alpha transparency. And it’s patent free.
