Three random-ish photos from Wikimedia commons could also work. That way you get some disconnect that forces the writers to find interesting ways to connect them rather than something more straightforwardly pulled from the image.

Clicked random and the last three I got were:
a sparsely wooded hillside
a high school basketball game
a gem with an icon of Christ engraved into it

Unless people on another board are really gung-ho about it, it's just another layer of complexity (and brings in other stylistic questions).
