jj,
it's illegal to take photos from other websites. even if you leave the watermark on it that say's 'AP', you are still supposed to buy it. st. john's buys the photos from AP (or maybe has an account with them, i don't really know exactly how it works) and is covering its bases by putting the 'buy' thing up there.
i know last year we were going to buy a photo from AP for the torch and it was like 100 bucks.
