Highend Theme – Presentation Slider image not aligning for mobile

Hi there

I use Highend Theme on http://www.kristiefogarty.com
On the main page I have a scrolling page with 4 presentation slides. The first one is a photo of me and it looks great on my desktop.
However when I view the page on my mobile it does not re-size to display me, I get cut off to the side.
Is it possible to use code to resize this OR can I replace the first presentation slide with another layup that will auto-size?

Thanks in advance.
Kristie
