Windows Central Question

When a picture is displayed on the screen, there is no method to go back to home screen. I have been rebooting phone to remedy but know there must be something that I am missing. Help?
 
Swipe from the bottom once, and the usual buttons will appear in the usual place. The orientation depends...

If you swipe for the second time the buttons will hide again.
