The short answer is No.  The longer answer is that people have been
doing it for years.  HP's own email system for the 3000 stores all
its data in an Image database, including messages and attachments.
This is all done manually by breaking the "blob" up into chunks and
storing each chunk in a separate detail record.  So don't let the
fact that Image lacks an official "blob" data type prevent you from
considering using Image to store your more lumpy data.

Personally I'd like to see Image support for something like blobs
so that I could store Java Objects in an Image database.  We're
starting to see an increase in interest in Object Oriented languages
on the 3000 (Java, C++, possibly Object Cobol, etc.) and some way
of turning Image into a pseudo OO database would be a good thing IMHO.
