making link from "categories" directly to product

[Nicolaj]

Hi,

 

I want to make a direct link from the categories in the left column to the /classes/productsales.php (I think it must be that file that goes directly to the three image selector) in the middle column. (in other words I want to to make a direct link like in html)

 

Do I have to look in classes, controller or variables to control links???

 

I understand cmv (prestashop) and enough php.

 

Hope somebody can save me time.
