Sherrie,

it matters very much which software has written those
old-style JPEG TIFFs, because it's not possible to
implement the original JPEG-in-TIFF specification,
only to misimplement it, and therefore every
TIFF-writing program does it its own, slightly
different way.

This is also why the TIFF library does not support
this old-style JPEG compression at the moment, only
the new, better style.

I think your best bet is to find a utility that *can*
read your old-style JPEG-in-TIFFs and convert them to
another TIFF compression method, like LZW. Maybe your
scanning software comes with something.

Cheers,
					Gerben Vos.
