Advice on URL/controller structure and "permalinks"

I think your problem is not specific to photo galleries - the same thing will happen to any content that has tags (for example) as there's several ways to arrive at the same place.

The only way to prevent that, as I see it, is to have unique URLs for every thing but for the context (what stream you're in, what tag set you're in, what filters you've got, etc) you keep that in session data.

As I mentioned before, I think that's really ugly. If Google reckons that my pictures of lizards, plants and bridges are a sly attempt to sell something, and so rate me lower, because there's several different URL's that contain the same image & text .. well, I guess somehow I'll find a way to struggle on with my life. If your site's a commercial proposition then I guess you can't be so insouciant about the matter.

Oh - my site should be back now, btw. Went a bit haywire yesterday - shouldn't have, though, as I was just munging around with some unrelated VM's on the server. Oh well. Computers are like that.
