According to the official PNG home page (http://www.cdrom.com/pub/png/): PNG (pronounced “ping”) is the Portable Network Graphics format, a format for storing images on computers. Unofficially its acronym stands for “PNG’s Not GIF.” PNG was designed to be the successor to the once-popular GIF format, which became decidedly less popular right around New Year’s Day 1995 when Unisys and CompuServe suddenly announced that programs implementing GIF would require royalties, because of Unisys’ patent on the LZW compression method used in GIF. Since GIF had been showing its age in a number of ways even prior to that, the announcement only catalyzed the development of a new and much-improved replacement format. PNG is the result. PNG has a variety of features.
