I’m trying to get a slideshow running on my TV from my photo collection on my PC. 
I tried setting up a Plex server on my PC but the Plex app has no interval setting and the slideshow is way too fast.
Then I tried a bunch of different chrome-casting apps to show the slideshow but they all stop running the slideshow when I close the app (turn off phone)
Is it possible to do what I need with what I have? (Android phone, Chromecast on my TV, Plex server om my PC)?
It seems to be a simple thing, but I can’t figure out how to solve this?
