-A PIC file contains embedded [[JPEG]] data, but it lacks the critical DQT segment(s), and may lack DHT segment(s), so it can't just be extracted as a standard JPEG file. PIC format compression  replaces the JPEG Huffman encoder with the proprietary ELS entropy encoder for 15% more compression.

-Though the PICView software give the impression that they are different formats, it's not clear that there is any distinction between PIC and [[KQP]]. If there is a difference, it could be that KQP is a restricted profile of PIC, and/or that KQP files are the ones that lack a JPEG "DHT" segment.
