YES! There are simple navigation controls that you can use on the TESLA Screen while using EV Slideshow For TESLA. The major one is the ability to “hold” on a photo by just tapping on the image while on the screen. The photo slideshow will pause on that image until the photo is touched again to begin the slide show again. Also at touching of a photo, you will see a left arrow and a right arrow appear on the sides of the image. You can go back an image or forward an image by depressing these buttons. (Depending on screen sensitivity and internet speeds).
Also by putting your Tesla screen in FULL PORTRAIT screen mode (Not half screen), you will be able to see the slideshow photos lined up in a linear fashion. You can jump to any photo in the lineup by touching the photo. The slideshow will continue from that selection.
