Unbeknownst to you (Time Inc.), your users are web 2.0 savvy. They are not necessarily interested in printed framed copies of photos, but in digital versions that they can use in a variety of ways. Many don’t want to use the images illegally, so they expect to understand how to gain legal access to the images. And if older images are marked as not being in the public domain, they need to know why.
Unfortunately for you, if you don’t tell your users what you expectations really are and give them the correct tools, you’re going to be disappointed with the results.
