Huygens will have descent imaging
some 1100 photos during descent to the surface
The planned images are for descent rather than post-landing, so the camera must (I'm quite sure) be built into the underside of the lander. No-one is (as yet) sure of the surface conditions, so it seems mission designers opted for the next obvious bet - images during descent. There may be an extra camera somewhere else on board for post-landing imaging, but I don't know (haven't heard so ..)
