Behind the scenes, Pinterest and Getty Images have been discussing Picscout.
Content owners, photographers, etc., some, have been concerned about proper use of the content and photographs, because of the past Pinterest Terms of Service, now, revised.
But, concerns still remain about proper attribution of copyrighted images. Which in reality is any content, as content is copyrighted at its creation.
But, proper attribution to the creator along with a trail of links or pins in this case, is what many want.
