A unterminating loop usually indicates that something
is too large to fit onto a page all by itself.

It might help to scale down the image.

There are a lot of factors which influence rendering,
it is hard to deduce this from a XSLT snippet. You'll
have to post a small but complete FO document which
demonstrates the problem. You can try:
1. Run your XML+XSL through Xalan or Saxon to get a
  FO file. Run this through FOP to confirm that the
  problem is still there.
2. Minimize the FO file by deleting as much stuff as
  possible from  it while still showing the problem.
  In particular, delete unnecessary fo:external-graphics.
  Try to delete stuff like font-size and fint-family as
  well.
3. Try to replace the offending image by a black GIF of
  the same height*width (in pixels) and check whether
  the problem persists.
4. Post the remaining FO file and the h*w of the image.
