Clickable product thumbnails

Hi
I use the theme ecommerce gem child. Love the theme, but I really would like the product thumbnails to be clickable and send the costumer to more information of the product (instead to directly buy the product). For more information of the product they have to click the small text under the thumbnail, and I dont think that is very customer friendly.
Are there a code to use for getting this thumbnaile clickable?
