The Media Cycling app lets you list a sequence of images and app it to the campaign timeline or playlist loop. Each time the app is displayed, a single image from the App list is shown. After all medias selected are presented, the app will reset and start again from the first media.
Any time you need to update the images displayed on screen, you just need to modify the app and hit "Save". All modification will be synchronized on screens app is published.
