Proving Creative Commons Licensing of a Work?

Q7U asks: "I recently posted a few Creative Commons licensed photographs from Flickr on one of my websites. I later noticed that one of the photographers had retroactively switched all of his photos from the Creative Commons license to an 'All Right Reserved' notice. When I saw this I went ahead and removed his photo (even though I understand that CC licenses are perpetual unless violated), but this begs the question: How does one prove one obtained a work under a Creative Commons license, should there ever be a dispute between a creator and the licensee? Is a simple screenshot of the webpage where it was offered proof enough? Any thoughts or suggestions would be appreciated."

    If someone has made photos licensed under CC, if I were going to use them, I'd be sure to obtain permission and verification first.

    That's the whole point of CC. The licenses are permission. If you have to get permission anyway, then what the hell is the point of CC in the first place?
