And what I mean by that is, if user X uploads 50 images, the first two pages of index will all be his or her shots. If we limited it to, say 3?, per user, then we'd see three of his/hers, followed by the most recent 3 of other users. Clicking on "x's photos" would of course get you all by that user.

I don't know if we'd want to extend this to the photos-by-tag page too. Maybe I'll throw together a couple of different views and ask for feedback...
