One idea they discussed involved a button that would allow a Pinterest user to ask a content owner for permission to pin. Right now, the issue is that "their lawyers say you can't pin anything that you don't own … but the site is saying you can. It's very confusing to users," she explains. "The quick version of the law is [that] you can't use someone else's stuff." Some photographers have been irked at their pictures showing up on Pinterest, and Flickr added an opt-out last month for users who want to make their images un-pinnable. The Journal also has some tips for using Pinterest safely, and Kowalski's full blog post is here.
