Bob, that's interesting. I can't replicate the behaviour, but I think Photobucket has made a system change somewhere so that, no matter what you click on, the link redirects to the "s" address. I always post links to the "i" address, but when I click on them from the forum I see a new tab open, the "i" address appears briefly in the address bar and is then replaced by the "s" address. If you click on the link to one of offroadfx4's pictures in this thread, you'll see the same thing happen.
Even if you copy the link to the "i" address and paste it into your address bar, it will redirect you to the "s" page. Try this link to offroad's picture,

Edit: I can't' even display the "i" address pages of my own photos when I'm logged into Photobucket. It's very odd.
