How to Set the Lock Screen Wallpaper on an iPhone

Open your iPhone's Settings. This is the grey gear icon on one of your iPhone's Home screens. It may be inside of a folder named "Utilities."

Scroll down and tap Wallpaper. This is in the third group of options.

Tap Choose a New Wallpaper. It's at the top of this screen.

Select a Wallpaper photo location. You can choose a photo from the following locations: Dynamic, Stills, or Live (iPhones 6 and newer) - Choose an Apple-created background. "Dynamic" and "Live" both move, while "Stills" presents a high-definition photo. Your camera roll - Choose a photo from your existing photo library. You'll see all of your albums displayed here.

Select a photo.

Choose a display option. Your typical wallpaper display options include the following: Still - Display the photo as it appears normally. Perspective - Zoom in on the photo. Live - Display a dynamic (changing) photo. You can tap and drag the photo to re-position it here.

Tap Set. This is at the bottom of the screen. You can also tap Cancel here if you want to choose a different photo.

Select Set Lock Screen. Now you'll see your selected photo whenever your iPhone's screen is awake but locked.
