Set the log level to LEVEL_DEBUG so you get more hints about what's
wrong when you're having problems. And check the the output written to
the console by the servlet. If you had, you would surely have seen that
FOP complains about not having found the image.
It also helps if you just do the XSLT transformation on the command line
(as I suggested earlier). By checking the generated FO afterwards you
can see if everything is alright.

This is wrong: Use {$image} instead because @image accesses the "image"
attribute of the context node, not the parameter.
