Simple full screen image display from external url

I’m brand new to this Roku dev. I have a png image with a guaranteed dimension of 1920x1080 from an external url that I need do display full screen. What’s the best approach for this? I’ve been playing with the Poster node but not been having any luck, its just displays a blank screen.

here’s my xml:

<?xml version="1.0" encoding="utf-8" ?>
<component name="MainScene" extends="Scene"> 
	<children>
        <Poster
        id="testPoster"
        uri="https://hello-screen-development.s3.amazonaws.com/large/rendered-image-1.png"
        width="1920"
        height="1080"
        translation="[160, 8]" />
    </children>
</component>
