Error messages and Google: my favorite combo. To summarize:
The TIFF file format permits programs to include information
which only that program understands. TIFF files produced by
programs that do this are not always readable by other programs.
and
End result: if you get your hands on one of these "old style
jpeg in tiff" files, you're pretty much out of luck. You'll have
to negotiate with the file supplier to provide it in a different
format.
Hope this helps.
