Woocommerce single product layout

Hi!
In my single product page, the layout of the <div> that contains the image and sub-images (div.images.hb-woo-single-images) are above the <div> that contsins the rest of the product info: product name, short description, add to cart, etc.(div.summary.entry-summary).

How can I change the layout (hopefully using CSS) to put both <div> in the same line? Like the example of your “Shop-Single Product” demo (http://hb-themes.com/themes/highend_wp/shop/shoes/nike-roshe-run/).
