App inventor how do i change the background image of my code using one button?

[AC Question]

Firstly I am trying to get my background image to change and I'm not sure how to change it using one button. my pictures are called image 1 and image 2 and I have a separate image for the background image of the canvas. I can do this relatively easily with two buttons but the task I am doing requires one. any help would be appreciated and thanks in advance
