- In the Settings app, tap the Picture Frame bar in the left-hand pane—it's the fourth item down, below Wi-Fi, Notifications, and Brightness & Wallpaper.
- Select "All Photos" or specific albums in the bottom of the right-hand pane.
- Specify the amount of time you want each photo displayed, transition effects, whether to zoom in on faces, and whether you want the images shuffled in the right-hand pane.
- Put the iPad in sleep mode and press the Home or Power button to wake it back up. Don't unlock the iPad. Instead, tap on the flower icon just to the right of the "Slide to Unlock" bar.
