It wasn't long ago that Flickr lamented the "cost of lost good will" its Wall Art service caused, but the photo-minded outfit thinks it has a solution: removing Creative Commons-licensed photos from Wall Art's available photos. What's more, the outfit is refunding the sales of CC images made through Wall Art as well. As Flickr vice president Bernardo Hernandez notes on the company blog, Wall Art's photo printing service will continue. However, the only works you'll be able to buy will pull from the Flickr Marketplace artists and stuff in your personal collection. And if you're interested in still selling, Hernandez urges you to sign up for Marketplace for consideration.
