We have a lot of JPEG images about which lack anykind of infomration in them. For the SDSS images we are thinking of adding infomration to a comment block. Perhaps this would be good in other instances also.

Currently we are thinking of adding something like Author="SDSS Collaboration "
Info="http://skyservice.jhu.edu/develop/jpeghead/index.html" TITLE="SDSS Image "
CRPIX1=744.5
CRPIX2=1024.5
CRTYPE1=RA--TAN
CRTYPE2=DEC--TAN

CRVAL1=179.948240689264

CDVAL2=0.000109924630958157
CDVAL3=0.000110062460780114
CDVAL4=-4.78845056498477E-08
