Size image beyond screen

site: vacationrentalgalena.com

I understand how to make the height of a slide larger as well as the width. However, what I’d like to do is have the slide show span the width of the page as you see here:

Current height and width of the biggest image on my page (vacationrentalgalena) is h2161 w4884. But it still stops at the content width. So how do I change it to go to the edges of the page?
thanks.
