Topic: random sets of images

Is it possible to have the images loaded and updated randomly? I'd love to just point to a directory and Tiltviewer then does it's thing...
I am not a flickr user and won't be, i have my own gallery with thousands of images that are accessible by mySQL queries.
If your answer is no, do you plan to offer this kind of feature or do you have any idea on how to solve it someway else?
