WhyPic is a compressed image file format and associated software, developed by Osamu Yamaji. Most of the information about it is in Japanese.
Files begin with ASCII characters "
- Possible format documentation at ypc12os2r2.lzh → SOURCE.LZH → FORMAT.DOC
- http://nyaos.org/VA009797/warp/whypic.html → ypc12os2r2.lzh (Seems to be an OS/2 port)
- ypc12os2r2.lzh → SAMPLE.YPC
It would be nice to locate a copy of the original software, which was in files named whypic10.lzh, whypic11.lzh, and whypic12.lzh.
