Slide Show shows a full screen version of your wallpaper and prevents your screen from turning off, so that you can use your Pre or Pixi as a digital picture frame. Currently, Slide Show only changes pictures when your wallpaper is changed by another app that cycles your wallpaper, such as Switcharoo or Flickr Addict. *** Please note that the current version of webOS will not allow us to use local images, that you have saved on your device. Follow the support link to inquire about obtaining a version of this app that supports local images ***
