VideoStudio :: X6 Ultimate - Multi-picture Slideshow

Basically I do a lot of dog rescue/foster stuff and doing videos (even if they are slide shows) of the dogs really get adopted. I am "ok" at doing a normal slide show. Here's a link for one I have already done

But, I would like to "spice" them up a little. One thing someone suggested was doing a slide show, like above, but having multiple pictures on the screen at once. For instance a picture appears in the Upper left, then upper right, then lower left, then lower right. So there are 4 pictures that are on the screen at the same time, but appear at different times. Like if you were showing some one snapshots and setting them on a table, with some covering up others.
