Problems with Assigning Photos as Directory Logo's

Hi, Many congratulations on a splendid and easy to use piece of software. I am struggling on one thing and perhaps you could offer me some advice on how to over come this problem.

I have a folder inside which I have created two sub folders.
I have assigned the pictures to appear as a directory logo at the sub folder level but dont seem to be able to find an option which would allow me assign a photo as a directory logo at the root level.

Any help would be most appreciated.
