Random hero header image on refresh

Bear with me, concrete5 NOOBY here! My goal here is to have a page randomly pick a hero header image on refresh from a set of, let's say, 5 images. I also want to have the ability to add a common caption for all images. The caption should be horizontally and vertically centered in the image! Im trying to get away from an image slider. Is this possible?

I already tried using the "Random Image" add-on but that does not allow me to add a caption.

Any help is appreciated!
