J2K w skrocie
J2K
JPEG 2000 arrived as a major standards effort to improve on classic JPEG, but its practical adoption concentrated in specialist domains rather than in the universal browser-and-camera role held by JPEG.

PPM
PBM, PGM, PPM, PNM, and later PAM come from the tool-centric tradition of keeping image interchange formats easy to parse, script, and transform.
