[theme: Blaskan] embedded slideshow does not resize well

I am testing the theme on a local host. I embedded a slideshow in a blogpost. It is 427 px width and 356 px height. It does not resize well when viewing in Iphone testsite. You have to scroll to see the whole slideshow. But Blaskan is a responsive theme, so it should be ok. Any idea what the problem is?
