SCREENSHOT QUESTION

I'm working on some hand drawn stuff that I plan on implementing into my game.
So I think I know how to change the main image for my game, I went to edit image and it had an option for changing the main image, but now I'm wondering something else.

Can I change the 4 display images on the games main page?
I like the current ones but I may want to swap one or two out for a different screen shot once I post the game's update.

Thank you. Sorry it took me so long to say that I've been really busy.
