VFB Background ( Foreground )

I would like to see a feature added to the VFB Background for foreground objects to have the option to scale the image larger or smaller in proportion. The only way around this is to do this in photoshop and change the lining size ,or make a plane with a image and scale which is not very intuitive. Sometimes I need to scale the image in the foreground if I need to move in closer with the camera.

Would be nice to have layers directly in the foreground settings similar to photoshop to have multiple items as well.
