Multiple-image Network Graphics is a public graphics file format for animated images.
MNG is closely related to the PNG image format. When PNG development started in early 1995, developers decided not to incorporate support for animation, not least because this feature of GIF was seldom used at the time. However, work soon started on MNG as an animation-supporting version of PNG. Version 1.0 of the MNG specification was released on January 31, 2001.
MNG is currently not as widely supported as PNG. Nonetheless, Gwenview has native MNG support, and MNG plugins are available for most other web browsers. Mozilla browsers and Netscape 6.0, 6.01 and 7.0 included native support for MNG until the code was removed in 2003 due to code size and little actual usage, causing complaints on the Mozilla development site. As a result, a MNGzilla project was started to offer patched Mozilla and Firefox browsers. By contrast, Firefox supports MNG rival APNG natively.
Neither Internet Explorer, Opera, nor Safari currently support MNG natively. Recent Sony Ericsson phones support MNG files in their themes. The Sphere game engine supports the use of MNG files for animations. GIMP can export images as MNG files. Imagemagick can create a MNG file from a series of PNG files. If MPlayer is linked against libmng, MPlayer and thus all graphical front-ends like KMPlayer and Gnome MPlayer can display MNG files.
Popular web hosting servers are not configured to handle mng files.
