How do you pick random image from a list?

I am trying to create a code where it picks a random image from a list and shows that pick as an image on the screen.

You should use the "select random list item" block in the list category.

one way to pick a random image; move the image to another list and remove image from the original List (alreadyUseImagesList).

Is this what you want to do. There are several ways to do something like this.
