"Flickr has hit a big milestone: users have uploaded five billion photos to the photo sharing service. \nThe photo (above) of the Woodward's building in Vancouver has been uploaded by a user called yeoaaron, and it's officially the five billionth photo on Flickr. For a bit of history, check out the three billionth and the four billionth photos here and here. \nAccording to Flickr, users upload more than 3,000 images to the site every minute. Although Flickr is the biggest social site that focuses on photo sharing, Facebook is still much larger with this regard; a year ago, it boasted 15 billion photos overall with 220 million new pictures posted each week. \nImage courtesy of yeoaaron on Flickr"^^<http://www.w3.org/2001/XMLSchema#string>
