slide show in media center

In windows vista home premium, in media center, with music playing, when I
play a slide show it shows pictures from every file on my computer. Does
anyone know how to limit the slides to pictures only and specifically more
than one folder of pictures? Any help is appreciated.

Go into the settings and click on stop watching folder. Select or de select
the folders that do not have pictures that you want to see. You can also add
folders to watch.

The stop watching folder only allows me to select or deselect the entire My
pictures folder, not any of the subfolders. Also, I only have 3 folders of
mine (+4 public) selected - My Pictures, My Videos, and My Music. But it
still picks up pictures from other folders.
By the way, I was in Media center trying to listen to music and it says I
must select folders in Library setup. I went there, tried to select my music
folder and it wouldn't let me. Is there some trick to "selecting" a folder?
