Yes.

In DocBook 4.0, <mediaobject> has been introduced to allow you have the same 
picture (or anything else) in several formats at the same time.

So the kind of tricks as proposed by Peter are only necessary for DocBook up 
to version 3.1 (I also proposed similar things at that time on this list).

The complete syntax for <mediaobject> is explained on
