Change Transition Speed and Playing Order
You can change the slide transition speed and the playing order of photos by tapping the More tab. The default transition speed is 3 seconds, and the playing order is to start playing the newest photo first, as shown in Figure 8.
Figure 8 The Speed section appears at the top, and the Playing Order appears at the bottom of the window.
You can change the number of seconds between photo slides by tapping either 1 sec to change the time between switching photo slides to 1 second, or tapping 5 secs to change the time to 5 seconds.
By default, the Gallery app scans your photo file information to see which photo was saved most recently and shows that photo in the slideshow first. Then slides are ordered from newest first to oldest last. If you’d prefer to play the slides starting with the oldest first, tap Play from Oldest in the list.
