Hi there, when you are setting your background photo for the Messages app, you either choose a preset choice such as water or aurora, or using the Photos app. It’s still a bit unclear what your asking for, but here’s my interpretation.
When you choose one of these, you will see a checkmark in the top right corner of the window that opens up. If you click that, it should upload the background image you want to have. In steps:
- Launch the Messages app and open the chat you want to set the background in.
- Then tap on the chat you want. This will take you to the info page.
- Here, you have to tap on the Backgrounds tab at the top.
- As you do, you will get access to a wide range of backgrounds and animations. You can tap on each of the background suggestions to see how they will look in the chat.
- Once you are satisfied with a background, you can tap on the tick button at the top (Checkmark) and your chosen background will be applied for you and your friend right away.
