Flickr, a leading photo sharing and social media site, has announced they now have had 3 billion photos uploaded to its service.  It has shown a 50% growth rate from nearly a year ago announcing its 2 billionth photo uploaded.

Although impressive, Flickr is still lagging behind the #1 photo sharing site: Facebook.  Facebook announced last month its 10 billionth member photo.

Flickr, acquired by Yahoo in 2005 for 35 million, has proven itself one of the finest acquisitions made in the Web 2.0 era.  Youtube was acquired by google for 1.6 billion and Facebook received a 15 billion valuation from Microsoft when it purchased a $240 million dollar stake in the company.
