I haven't had a problem, I have a PPT that does exactly that, it automatically goes from slide to slide, then at the end, loops back to the beginning..... The looping is done within the PPT, and it works quite nicely. You can cut the PPT into a series of images, then load those as a group that loops, saves loading the helper app, but then it's a lot more work for you to do, especially if the PPT comes from someone else.<br>
