An anonymous reader writes "Photographer Maxwell Jackson went to an event called The Color Run and took some pictures. He was approached by the organization to share some of his photos on Facebook, and he agreed. Later, he found they were being used without attribution in promotional materials such as flyers and signs. When he contacted The Color Run over the misuse of his photos, they sued him. As a professional freelance photographer for a local college and a hobbyist code junky, I'm intrigued by this story and how it should be a warning for members of either trade. There is a good lesson to be learned here about taking for granted the legal implications of the manner in which you exchange your own intellectual property with anyone."
