Slide show when in dock mode

Now that I have a dock for my desk (ezeStand), I've been playing with the slideshow. It seems like it goes through all of the pictures I've taken with the Droid camera. Is there a way to select which pictures I want? Some of the pictures are of mundane things, not things I really want in a slide show. When I tried searching the market place, all I seemed to find was slide show widgets that appear on your regular set of home screens. I'm wondering if there's anything particularly for the dock mode. If not, I guess I'll start playing with the other apps.
