How to create a one-inch, two-inch, and six-inch photo

How can we make one-inch, two-inch, and six-inch photos? I hope you don't have to worry about using one-inch photos anymore. Just make your own photos and print them directly!
First, you must know the quantitative relationship:
6-inch = 10.2x15.2
1 inch = 2.5x3.5
2-inch = 3.5x5.3
1. Open the photo you want to create
2. in the toolbar, click crop tool (adjust width: 2.5 cm, height: 3.5 cm, resolution: 300 pixels), select a proper position on the photo, click the attribute bar (OK √) (for example)

 

3. Image image size: (adjustable width: 0.4 cm, height: 0.4 cm, relative: √) Click OK (for example)

 
The effect is as follows:

 
4. Click "edit" -- "define image" to define the cropped photo as a pattern.
5. Create a canvas: Click file-New (adjust width: 11.6 cm, height: 7.8 cm, resolution: 300 pixels/inch) (for example)

 
6. Click Edit-fill: (use a custom image and select the image you just saved) (for example)

 
Final effect:
