Sidebar – well sort of

I am attempting to creat a photoblog theme, yes I know it has been done, but I can find nothing to meet my requirements. What I have is a <div> for the photo, a <div> for the exif data to the right of this; and I want a sort of sidebar that will live below both of these, and above the footer, with basic meta data. My problem is that I am not quite sure how this can be achieved, any ideas would be much appreciated, I know that the solution will be blatantly obvious when I see it but it is sometimes difficult to see the twig when standing in the middle of the forest.
