I still like the Themis distribution site better
where you can easily get to each image's context images, which makes it so much easier in trying to understand what the processes at work are...
the other major annoyance with the MGS images is that they continue the rather futiel search to find large amountsof water on Mars, wheras both they and we would be much better served by focusing on the small water traps, "volcanism" with shergottite mud, and CRATERS.
all best,
