Using System Preferences Settings
- Click on the apple icon found on the top left corner of your screen and then select on the “System Preferences.” It’s the second option on the list of the menu. Alternatively, you may get it pinned on your Dock as a grey-gear like an icon.
- Next, click on the “Desktop & Screen Saver.”
- Click on the apple dropdown located on the left side of the “Desktop” panel and then click on “Desktop pictures” and select the photo that you want to set as your background. In the same section, you can also choose to change pictures at intervals. To set your photos to be changing, check on the box next to the “Change picture” option located at the bottom center and then set time interval for changing the picture from the dropdown box. And if you want the photos to be a shuffle, check the “Random order.”

- Click on the dropdown menu located on the left or click on the + sign on the bottom left corner. Select on the folder having your images, and the folder will automatically get added on the bottom-left screen.

Using Photos Application
- Launch your photo application (Photos or iPhoto) depending on the app that you’re using. If you’re using other photo apps, this option may not be there. These steps work correctly on iPhone 9.5 and the later versions, but the earlier versions may have some differences.
- Select the photo that you want to use. Ensure that the picture you’re selecting is saved on your computer, but not on Camera or iCloud library. If you’d wish to use the images in your iCloud library or camera, drag the images and save them on your computer.
- Click on the “Share” option on the upper right corner
- Then, click on “Set Desktop Picture “after that, you can continue on display and select a suitable alternative that fits your preference.

Select the image you want from your Photos app and click on the “File” tab and then click on the “Export” and finally click on the “Export Modified Original.”
If using the iPhoto app, click on “File” and then proceed and click “Reveal In Finder” and finally click on the “Original.” Alternatively, you can open the iPhoto app and then right-click by holding the “Ctrl” button on the keyboard and then tap on the image you want to set background picture, then choose on the “Show File” for the photo to reveal in Finder.
