Image fullscreen like video

Introduction

Looking for a full screen image feature

User Story

For a few customers, we have created a layout with several layers. One of those layers is not 1920x1080 but 1600x900. Also several other layers are also included as in, time, date, weather forecast. Some of the included movies are going fullscreen, but imaged are not possible. They stay in 1600x900.
We are seeking a feature/solution they also get images to fullscreen from a resized layer that is not full screen.
