Software that came with our digital camera allows you add text (description
of photo say) to the jpg file. This is NOT printed on this image, but is within
the file so that the cataloguing tool can find it. This is useful and intriguing
but what I really want to do is to add text, not by their software, but from
inside our metadata database client. This means using the same entry as
was made into some metadata fields (which of course is structured). Person
only has to enter the information once and it remains attached to the jpg if
someone looks at using the photo catalog tool.
The trick is: WHERE in the jpg file format is this text actually being stored.
Anyone know JPG internals well enough to comment?
