I wonder how hard it would be to simulate these photos in Orbiter. A quick search here came up with nothing as far as a Mars Express add-on, but that actually is a minor problem. If one had the orbital elements of Mars Express for the time frame of these outstanding photos, any Orbiter spacecraft could be put in the right position at the right time to simulate them...at least in theory.
