DOCBOOK-APPS: Getting images into PDF

Hi,

I've been trying to get graphics into PDF from Docbook.

The tools I am using are OpenJade 1.3 with OpenSP 1.3.4, DSSL stylesheets 
1.71 and pdfjadetex from 17/04/2001

I have tried various graphics formats for the <imagedata> element, 
including PNG, JPEG, EPS and PDF. None result in a graphic in the PDF 
output; EPS and PDF actually leave space in the resulting document, but no 
picture.

I have looked at the archives - others have been down this path - but can't 
find the magic recipe to make it work!


Thanks for any help.



Dave
