Google Images Mislabels Many Copyrighted Pictures

PDNPulse: Google Images Mislabels Many Copyrighted Pictures:

How could this happen? Apparently, Google assumes images are copyrighted unless they are identified with a Creative Commons or GNU Free Documentation license, or are labeled as being in the public domain. The system relies on Internet users to properly identify the status of the images they publish. Unfortunately many don’t, particularly on the Yahoo!-owned Flickr site.
