On the home page of my website (http://www.historyinyourownbackyard.com/) I have two lower rows of pictures. I would like to have 4 full lower rows of pictures as shown on the home page of this Fullscreen theme: http://www.clouds365.com/ so that people with larger screens have a "fullscreen" of pictures.
Does anybody have any idea on how this is done? I'm a rookie when it comes to making a website (My site was setup by a "web developer" who doesn't know how to do this.) so if you could dumb down your answer for me, it would be greatly appreciated.
