Well, in my case I don't want search engines to follow them-- in fact they're blocked from the whole directory containing the page ;) So far only in robots.txt, but I should probably add a rewrite along the lines of "if you've got 'spider' in your name, get lost".
Giraffoto, I don't know who your target audience is. For the one I'm talking about here, it's aimed at people who know the organization and/or its members in real life. That can make a big difference, so think about who will be looking at your pictures.
