Moving an image contineously

[onwire]

I have six images and I want to move them at the slide bottom contineously
without any break. Example. as it happens on CNN or BBC that text bar moves
continueously without stopping or breaking...

There are probably better ways, but one is this:

Group the 6 images.
Drag them off the left edge of the slide.
Right-click, choose Custom Animation
Add Effect
Crawl In, hit OK
Double-click the animation in the task pane, choose Timing tab.
Choose "repeat until end of slide."
