How to change the Wallpaper on your iPhone

How to change the default background image - or Wallpaper - that appears when your iPhone is locked

The Apple iPhone does not have any easily installable themes (and hey why would you? It's beautiful already) but you can change and customise its default background image (or Wallpaper).

Out of the box this is the striking image of planet Earth as seen from space, chosen because it shows the capabilities of the iPhone's 163 DPI screen. But if you get tired of looking at the beautiful blue globe you can change it quite simply in either of the following ways:

Method 1

1. Click the home button to go to the main menu. Then click on Settings
2. In the Settings screen click on Wallpaper
3. You have a choice of options:
   • Wallpaper will take you to Apple's preloaded range of Wallpapers. To switch to a new one, click on its thumbnail image
   • Camera Roll lets you select from any photos you have taken with the camera. Select the one you want by tapping it
   • Photo Library (and any photo folders you have created) lets you pick from any photo you have synced with your iPhone. Select the one you want by tapping it
4. Once you have selected the photo, you can drag your finger to move it into the position you want and use the finger-thumb pinch to zoom it in or out. When it looks right click on Set Wallpaper

Method 2

1. Click the home button to go to the main menu. Then click on Photos
2. Find the photo you want and tap once to make the control overlay appear. Click on the Actions icon in the bottom left corner
3. You can drag your finger to move the image into the position you want and use the finger-thumb pinch to zoom it in or out. When it looks right click on Set Wallpaper
