Header image not scaling on desktop

Hi,

I am using the Sydney theme and love it. I have a header image on each page and when you look at the site on a mobile device the header looks great but on the desktop computer the image is huge and doesnt scale. When you change the size of the browser window the image scales correctly for mobile but when you adjust the browser size for the desktop the header image gets huge.

Any thoughts?

Thank You
Joe
