The "official" JPEG file format. Part 3 of the JPEG standard now includes a
fully defined file format to storing JPEG data. 

When the JPEG format was standardized, disagreements among ISO committees
prevented a standard JPEG file format from being created. The defacto format
that appeared was JFIF from C-cube Microsystems. The JFIF format, although
now quite wide-spread, is very limited in capability as file formats go.

SPIFF is intended to replace the JFIF file format, adding features (more
colorspaces, a recognized way of including text blocks, and so forth),
and provding a backwards-compatability allowing SPIFF files to be read my
most JPEG/JFIF decoders. JFIF, however, has a five-year head start on SPIFF,
so the likelyhood of it being completely replaced anytime soon is not good.

SPIFF's very first journal article has appeared:

  SPIFF: Still Picture Interchange File Format, Dr. Dobb's Journal, 
    James D. Murray, #249 July 1996 (Vol 21, Issue 7), pp. 34-41.
