Scrolling Panoramic Thingy

Sorry for the lack of technical reference, but I am trying to figure out exactly what the flash banner is in this page:

Obviously, I need to duplicate something of the sort, though I want to tone down some of the more obnoxious effects. I have seven pictures that I want to display in a scrolling slideshow kind of effect as in the site above, but I don’t want it to autoscroll, I want it to go left and right on demand. I have a pretty good idea how to do that (easy nextframe actions), but I need to display the previous and next picture as well.

Can someone give me the proper nomenclature for that kind of control so I can at least google in the right direction?
