Double The Image ERROR!!!

Hi
Ive installed the plugin.
But instead of it flipping the image it displays the image one on top of the other.
So My original featured image displays but the second thumbnail displays directly below it.
I am using Boemia Free theme and on their demo page I believe they have this plugin and it works fine.

Thanks!
