Ok so I'm totally clueless when it comes to this stuff so you have to treat me like I'm mildly retarded and be extremly detailed, provide links to the actual mods and or draw me a map. lol

So my website is www.wittlethings.com

Right now it's set up to show as a list of my products. When you go to photo birth announcements - all birth announcements it shows one after the other.

I'd like to change this to a gallery style. Like this website here:
http://www.weddingpaperdivas.com/sho...date-cards.htm

I'd like maybe 4 products across by however many rows, versus the list.

I did a search and found some info on

Column Layout Grid mod

but I have no idea where to get this mod out and when I search google it comes up with this threat but nothing on the mod itself or where to dl it or how to install it.

Can someone please direct me where to get it (with a direct link "Please) and how to install it?

Thanks!
