PMS doesn't show picture library

[sdrph]

I'm a new user to PMS. I can view and play my video and music files but for some reason it doesn't see my picture library. I have the location added to the shared folders box but still no luck. All photos are .JPG format and I'm using Windows 7. Here is what my shared box looks like....

C:\Users\ralph\Pictures\My Pictures
C:\Users\ralph\Videos\Camcorder Video
C:\Users\ralph\Videos\Camera Video
C:\Users\ralph\Music\Flac Music


Any help would be appreciated.
