By the time she was leaving the airport, she was barraged with media requests. The photo has been viewed nearly one million times on hundreds of websites, but Stephanie was paid for the photo by only five news organizations. Stephanie doesn't feel slighted, but a professional news photographer would have been paid many times what Stephanie received. In today's climate, are amateur photos shared on Twitter or Facebook basically free for all websites to use? Is re-tweeting or re-sharing automatically fair use?"
