App with cloud to insert images from remote control

Hi guys, is there any tutorial/video or something that can explain how to create an app with images and i should control this images remotely. 

Example: 

The app is on the mobiles of users and, without the need to re-install or update the app, every day i can add new images and users can see them, A kind of "daily remote update"..

store your images somewhere in the internet, for example your web server or your Google Drive.

In your app then use the image component together with the link to the image
