However, when the presenter brought it up, he was speaking about THEMIS pictures supporting MER landing site selection. I can't remember his exact wording, so it's possible I jumped to a wrong conclusion?

Not at all, though I am surprised, given the orbital mapping cycles and repeat supercycles of Odyssey, which are very similar to MGS, that a single site would have been imaged between 50-100 times in the relatively short period since full-scale mapping operations have begun. I do know, however, from viewing some of the topo/image overlays of the MER candidate sites, that MOC NA swaths have given extensive coverage.
