MNG (pronounced "ming"), is short for Multiple-image Network Graphics. Designed with the same modular philosophy as PNG and by many of the same people, MNG is intended to provide a home for all of the multi-image capabilities that have no place in PNG.
Although the idea of MNG has been around almost as long as PNG has, serious design discussions didn't begin until May 1996, and even then there was considerable debate over whether to make MNG a dirt-simple ``glue'' format around PNG or a complex multimedia format capable of integrating animations, audio and even video. By mid-1998, MNG had settled down to something in between; while it has fairly extensive animation and image-manipulation capabilities, there is no serious expectation that it will ever integrate audio or video.
