Is it possible to have Picture boxes on an MDI form so the vertical ones take priority?

Currently, if you have a vertical picture box on an MDI and add a horizontal one, the horizontal one takes the MDI width and the virtical one is shortened to the bottom of the horizontal one. I'd like to be able to have the vertical one full height and 2 horizontal ones next to it.

I just wondered if there is a simple answer before I go into frames and handles and moving stuff around etc.
