This is how I describe it for customers. Use a wood canvas for your background image. This image can be your hometown, a vacation spot, or any landscape. Then, publish an image that you want to feature on a wood box. This image can be a specific building, your family on vacation, or a highlight from the background image.

Then, hang the box on the background canvas.
