IE 9 – slideshow stretches beyond width of screen

I cant figure out this random occurrence with IE 9 and this slideshow. The slideshow is excellent on every other browser. But in IE 9 it’s hit or miss. It loads for a second and looks fine, then it switches to very large and width and height wise and stretches beyond the right side and makes a horizontal scrollbar.

Any thoughts?
