If you post Flickr images using a commercial creative commons license, Yahoo has a little surprise: it will soon be free to sell them and keep all the money. It recently decided to peddle canvas prints of selected photos for up to $50, taking 100 percent of the revenue from creative commons users. That’s a 180 degree approach from a recent decision it made to split revenue with select users who stick to non-commercial licenses. The new policy has made many of the site’s devotees upset — especially pro account users — who say that while they’re fine with third-party companies using their photos, they’re not fine at all with Flickr itself selling them for profit.Though Yahoo isn’t breaking any laws, some feel it has broken the circle of trust with its large community of photographers. Flickr co-founder Stewart Butterfield told the WSJ that “it’s hard to imagine the revenue from selling prints will cover the cost of lost goodwill.” There is something that artists can do to stop Yahoo from using their work: switch the creative commons license to non-commercial. Unfortunately, such a scorched-earth approach would also heavily reduce the supply of photos available to other businesses or non-profit groups — meaning everybody loses.
