Yes, to do it with out root, look up "Rotating Wallpaper.apk" in Google and download it. You will have to side load it, but it doesn't require root. You do need to read the instructions, it has profiles that get set, but you just pick one picture and set that as the active profile. It also has a setting that makes the change after a minute, so sometimes if you turn the screen off and back on again right away, for a few seconds, (up to a minute), it will be one of the default pics until it switches to the one you set.
