This is super cool! We had a lot of fun with it. The only improvements I would suggest are:
* not repeating the images, having them shuffled is cool but I'd rather it just stop after showing everything once
* if it had the name of the image under / showed up when you got close or something?
* some of the images were randomly upside-down for some reason?
But overall we had a ton of fun going back and seeing old pictures! The ghosts were super cute too :)
