Android gallery app from cloud?

Hi, I'm trying to get an Android tablet for my parents living in another state, mount it to a wall like a digital frame, and keep it on the gallery app to cycle through photos of my life and what I'm up to. This app will display photos from an online account and cycles through them, this part is easy. Lots of apps currently do that such as Picasa. What I'm looking for is the an app that updates images "in real time", where if I delete and add images into the account online, the app will no longer show deleted images and newly added images will get cycled in, without having to restart the app. My parents are old and I don't want to teach them how to use an Android tablet.

Ideally, this will be a "set it and forget it" solution for my parents. Does anyone currently know of an app that does that?

Thank you.

I don't know of anything like that, but.

Can you just use a remote desktop app and do what you need to over wifi?

You can control an Android tablet via remote desktop?

and any cloud services installed on the android device would do it.
