Photo transition timing

Please create a Settings option to adjust the transition time between photos when playing a photo folder as a slideshow.

I was trying to showcase how awesome Plex is too many of my coworkers, and when I put together a folder of photos from one of our recent work events to show them, some pictures have seven seconds in between, some sit on the screen for barely a second. It makes Plex look kind of amateur, which it’s not!
