Do you see more of these license symbols? These are Creative Commons licenses and they are free!
Creative Commons offer an easy and save way to use and provide media online.
For example: You have a video clip of from a conference talk you gave, assign a Creative Commons license so others can use your talk but have to reference you. Or, you would like to enhance your PowerPoint presentation with some music, it is safe to use music with Creative Commons licenses. You are looking for an image for your presentation, google (advance search) for images with a Creative Commons license only.
