I am asking this question because I have just been looking at a post called San Diego Comic-Con (SDCC) 2013 in Pictures: The Creative Commons Edition [Gallery] which as part of the article says "Please note that all the pictures you see below are licensed under a Creative Commons license"

I like the way it is making it really clear that these images (and not other images) published on this site are Creative Commons. I have also noticed, when I copied the article title it automatically added an attribution,which is exactly the text shown just below this.
