On the site I am currently updating, the category and sub-category pages are laid out in a grid http://www.archiegranot.com/online-store-1/ and the product pages are laid out in a column with the info of the products to the right of the picture http://www.archiegranot.com/index.ph...index&cPath=33 .

How can I change the layout of the product pages throughout the whole site so that they also show in a grid with minimal info (with ability to choose what info is shown), where the customer has to click on the picture/text of the product to find out more and/or purchase the item?
