Hi Essexlad,
I created a very rough style to show you one way of creating the rolling text. It's quite simple and there may be more elegant ways of getting the same result but this will get you started. The style requires two pictures, one for the background and one for the overlayed image. You could just apply the style to some images and then copy/paste only the frame into whatever slide you are using to get the scrolling text effect.
