Customize Category Display (forum home)

Hi !
Currently working on skinning a 3.5 RC1 board, and trying to put the categorys inside a "box" like the attached images shows, made it just to show what i want.

I know it's possible to add images to the top and bottom of each category, but i need to add image to the left and right side also.

Anyone here that know what i should do and want to share the knowledge ?

Have been searching several hours without finding something, also been trying to find a way myself.
