Welcome to Lenovo Community Forums!
When you click the Photo tile on the Home screen, you get to pick from several picture libraries, including the one on your computer. From there, you can browse folders and watch the photos you wish to view.
To start the slide show, right-click anywhere on the screen and select Slide show near the lower-right corner.
Once started, you have some control over the slideshow. Pressing the space bar will pause the show. The left and right arrow keys will take you to the last or next picture. To start it again, right-click the screen and click the Slide show icon again.
Refer here to see how to start a slideshow using windows photo viewer.
Hope this helps!
