How about user control. Such as only 1 image a day... Or 010 images max.
I have a few users now so I am going to start having to control them...
Maybe a way to integrate it and a little favorite program of mine:

(So we could put a slide show on the home page.)
Like flicker can put in images through RSS Feed I think...
Just ideas.
