I'm wondering if anyone is familiar enough with a streaming device (Roku, Chromecast, Fire Stick, etc) that will allow you do put together a slideshow remotely (ie: on my desktop) and have it displayed in another room?

I'd like to have a slideshow playing on loop on two TVs in another room. I'd like to be able to edit the slideshow whenever I want from my desktop.

Essentially, I want ADs running on these TVs. New picture ever 5-6 seconds, en loop, forever. With a few clicks add/remove pictures.

It's not that I'm not sure if this can be done, it's just with so many options and apps I want to be sure I'm getting one that does this basic thing.
