play/pause buttons for slideshow

Site URL: https://www.ashtonography.com/

I have a simple slideshow on my site homepage. I have it set to autoplay, which is good - I want to cycle the images automatically. But, I recognize this can be annoying if the window is sitting half behind another window, etc, and it just goes and goes. 

Is it possible to add play and pause buttons so it'll still automatically cycle, but CAN be stopped if the user wants?
