Fullscreen image similar to CSS3 'cover'

Hi, I'm new to Adobe Edge Animate CC

I'm looking to make a simple fullscreen image slideshow and I'm having issues making the images fullscreen. They need to be similar to CSS3 background-image: cover.

This is my site design: http://snag.gy/1spAi.jpg

And this is a good example of how I'd like the images to scale: http://ringvemedia.com/

I'm sure it should be easy but I'm coming up blank. Any suggestions helpful.

Thanks
