display only one image instead of the product page for one specific category

[BINELLO]

Hi,

 

I need to change all product page display for some specific categories,

 

instead of my theme default product page I need to show only a big picture, only for 3 chosen categories

 

How can i edit product.css and .tpl for only those categories ?

 

I can't finish my work on the website for my boss until the product of the carousel on the homepage aren't "only image product page"

 

Thanks.

 

here the link for the website : http://www.stand3d.com/
