How do I add the product listing in columns to my configuration/product listing? I've downloaded the "column layout grid for Product Listing" (I believe that would be the needed additional add-on) but now I'm stuck. I'd like to list my products so they are displayed as 3-4 images next to each other with the title in small font below.

I'm using zen cart 1.3.8a, the zen template "lavender". My URL is http://fashionfoot.net

Thanks for any help you can give me
