Hi, I've put together a quick movie on how to use states to create an image carousel. We'll have a better version of this in a few weeks, but this should help get you going. It's about 10 minutes long and shows how to create a slideshow and then an image carousel. This was just thrown together at my desk, so I apologize if it's a little rough.
