Dynamic fullscreen Loader component

I’m trying to make a image slideshow that adjusts to the fullscreen of whatever resolution it is being played back on. I have an fscommand set up to extend the projector file to fullscreen but I cannot figure out how to make the images scale to the fullscreen value.

to call the images I’m using a loader component and xml. I thought I could simply set the loader component’s _xscale and _yscale to Stage.width and Stage.height respectively but that only resulted in a very strangely distorted image that took up a tiny part of the screen. does anyone know how I can set the Loader, and it’s loaded image, to scale to fullscreen along with the projector?

thanks in advance
