About .jng graphic file:

JNG was created as an adjunct to the MNG animation format, but may be used as a stand-alone format. JNG files embed an 8-bit or 12-bit JPEG datastream in order to store color data, and may embed another datastream (1, 2, 4, 8, 16 bit PNG, or 8 bit JPEG grayscale image) for transparency information. Actually, a JNG may contain two separate JPEG datastreams for color information (one eight-bit and one twelve-bit) to permit decoders that are unable to (or do not wish to) handle twelve-bit datastreams to display the eight-bit datastream instead, if one is present.
