JNG (JPEG Network Graphics) #44

JNG (JPEG Network Graphics)

is an image file format. It encapsulates a JPEG datastream, and adds support for transparency.

It is essentially the lossy-compression counterpart to PNG. It was developed so that MNG could use it as a building block.

Too exotic and old format.
