Flickr Commons is five years old and, to celebrate, Flickr has created galleries of the most viewed, 'favorited' and commented-upon images. The Commons was launched in 2008 with 1500 photos, in partnership with the US Library of Congress. Five years later, with several more partner institutions on-board, the collection of public domain photographs comprises more than 250,000 images. According to Flickr, these images have generated more than 2 million tags and over 650,000 comments. Click the links below to see the galleries of most viewed, liked and commented-on pictures, as selected by the Commons' member institutions.
