DOCBOOK-APPS: Docbook in Red Hat 7.1 - are the pictures there

Hi

I have an irritating problem using openjade.
I have many picures inserted in my SGML/DocBook source
using <GRAPHIC FILEREF="front.&magic"></GRAPHIC>

The &magic; I toggle using a Makefile from PNG til EPS
(for Postscript-generation)

The problem is the front.png (or front.&magic; to be
exact) might not exist. This I will normally not detect
before very late in the translation-phase - and only as
a warning (I think it is).

Any clues how to make a good hard ERROR :-) when a
picture is missing?
