How ai uses pictures as background. thank you

1. Start the AI software and create a new document. Then pull the picture into AI.

2. Click Embed.

3. Click the image description drop-down button to pop up the menu, and then click: low-fidelity photos.

4. Wait a moment, wait for the software to be processed, and then click Extend.

5. Click Expand, put the mouse on the picture, right-click to pop up the right-click menu, and click Ungroup.

6. Click the mouse around the picture, and then click the white background of the picture again. You can see that the white background is divided into several pieces, and we choose one of them.

7. Press the DELETE key to delete this block, and then click another block in the background.

8. Similarly, delete all the backgrounds one by one.

9. So, the background of the picture is transparent now, because the drawing board is white, so you can't see the effect now. We can see the effect by moving the characters to the periphery of the drawing board.
