Steady then ease

I’ve made a flash banner that has a sort of scrolling picture thing, kind of like the olde infinate menu. But the images aren’t a menu, their just decorative.

I used proto.layer51.com’s trusty ease everything prototype as the movement engine, but I’ve never used it on such a long item before.

Is there a way to make the pictures move in at a constant speed, THEN ease out when they’re about 85% done sliding in?
