Development of Creative Commons licenses

I am not a lawyer, I could be wrong, I don't remember the discussion  
we had about revoking the license offer.

IIRC: They are once you get them under the license. But you can stop  
offering them under the license.

If that is correct the flickr user can stop offering the work under a  
CC license. But anyone who already has the work can use it under the  
CC license and can pass it on.

flickr should add the license to the metadata of images. That would  
fix this.

And possibly Wikimedia Commons users should screengrab the image with  
the CC license next to it to prove that the work was offered under  
that license.
