Three Billion Photos At Flickr

A Flickr user named Garrett Ryan Smith uploaded the 3 billionth photo to the site today. The last big milestone was 2 billion photos, a year ago.

They’re well behind Facebook, with 10 billion. And they’re falling further behind – a year ago Facebook had just 4.1 billion photos.

Still, it’s a staggering number of photos for a site that launched in 2004.
