I added the second button and was able to make it flip with the scaleX = -1 property. I was able to make the photos loop with an if/else statement and they advance forward or backward with the right and left buttons and I was able to refresh the images by adding a reset function. My back button wouldn't work and I finally figured out that I had an extra bracket (for some reason I wasn't getting any errors) and now it works and I'm very proud!
