DOCBOOK-APPS: Including mediaobjects

Hello,

... trying for a while to include some graphics in my xml-docbook I'm 
currently running Xalan2.1, FOP-0.19.0 and the 1.40 XSL-Stylesheets by 
Norman Walsh against the attached file. My box is running Win98.

Has anybody a hint (or) HOW-TO include any images in my PDF's?

Where are they actually included? Does it FOP? Does it the XSLT-parser 
already?
Where have the paths to be relative to? Which syntax will I have to use for 
the file's path (or URL?)?
Is it simply a OS misbehaviour?


Ciao
