Vista - Question about picture library

Hi I'm new to the forums but I have a quick question about the media center picture library. I should probably inform you first off that I'm working on my xbox 360 media extender/center. I download all of my Album art and keep it with the music in individual folders. for instance my Nine Inch Nails albums are in individual folders with the album art in those same folders.

Now the question is, do I have to add those pictures to the picture library if I want to add my music? It seems to me that if I add a folder it adds everything in the folder which causes some problems for me. I simply don't want to view my album art(along with all my other pictures) when I hit "play slide show" under music>play all, as I'd like to have some pictures come up while I'm listening to music.

I have a dedicated folder for art I'd like to have on display when I listen to music. Now if there is another way to do this I'd definitely like to hear it as I've been trying to do this for a while and am getting slightly annoyed...
