Category listing on seperate page

Hi All,

I am using zencart 1.5 and a template from 12 Leaves.
The template has banner ads on the main page and a slideshow.

The menu above has links to featured products, new products etc.

What I would like is a link to the categories where when this link is clicked all the products in the category come up in a grid form on a new page.

When the customer clicks that category product they want it would then take them to the normal zen cart set up.

I know I can use a drop down list for the categories but I have a lot of categories and it would be good to have them all displayed in a grid with a picture ( similiar to what you can do with products )

hope this makes sense... any ideas would be greatly welcomed.

You can make a link to "index.php?main_page=index&cPath=0" and it will point to a page displaying all of the top categories.

Exactly where (in what PHP file) you put this link will depend on what categories-tabs or other top nav menu you are using.
