One of my great joys in life is walking people who create church or nonprofit newsletters through the very real dangers of using Google Images to find clipart. Not really.

"The internet giant has revealed that it will now include creator and credit metadata in photos it displays on Google Images, and in the coming weeks it will add copyright notice metadata, meaning visitors can see with a couple of clicks who the photographer was and who owns the rights. The creator is usually the person who took the photograph, while the credit may include additional parties or rightsholders who supplied the image."
