I decided on adding extra divs because I can maneuver the image around, up/down, left/right without affecting the other div's / box's so much. I can widen the wrapper div if need be. I used the box size width: 150px; min-height: 100px; only to hold open the box to make it easier to see the div's for this example I am working on.
Thanks for the tips. The .blah:last-child {border:none} when I looked it up at WC3 http://www.w3schools.com/ now makes some sense to me : )
