Don't have a digital camera, but I can tell you what I did - went to the lumber yard and bought a long piece of wood that's 1" thick X 12" across. Came home and measure the distance between empty shelves, and cut the long single piece into multiple single pieces of that length. Then, I placed them vertically between the shelves, so that the 1" side ran from top to bottom, and the 12" side ran from front to back.
Basically, it's the same theory as splinlps setup, only the vertical seperation between cubicles is added after the fact, not built-in. Guestimating, I'd say that one of my shelves is about the lenght of three of his cubicles, and I've got 1 1X12 support in the middle of it.
Hope that helps.
