Flickr’s 40 million registered users are being given the chance to make money out of their snaps. For the two years, Getty Images has tapped into more than 100,000 photos taken by professional and semi-pro photographers who post on the site. Now the doors are being opened to all Flickr users as Getty takes advantage of a library of four billion pictures. Neither Getty nor Flickr were forthcoming about actual rates saying they vary from job to job but are industry standard. It is generally thought the average rate for an image is between USD 150- USD 240. The agreement extends one that has been in place for the last year with photo library Getty. Under that deal, Getty built up its stock or archive photography base with pictures taken by pros or semi-pros posting on Flickr. These were then sold on to the firm’s commercial clients and photographers were paid the industry commission rate when their images were used. Users wanting to take part in the project will be asked to opt-in to the scheme.
