That's really an application issue. If it's convenient and you won't
loose significant information, then by all means, restrict the size. If
there's good reason to use large jpegs, go ahead.

I'd pick a negative subtype and lobby for the Firebird group to define a
few image types for permanent inclusion - not that we'll do anything
with them necessarily, but jpeg has become common enough that tools
might be able to use the type to offer jpeg rendering automatically.

Yes, store them in the same database. Cross-database work is a nuisance.

Sounds good.
