I use (and attribute) CC photographs all the time and I have to say that I wasn&#x27;t even aware of a couple of those requirements. Sadly, I think terms like these, as well as the optional non-commercial variant, are serious issues with CC. Attribution can be hard to carry along with a photograph consistently but at least the idea of a photo credit is pretty deeply ingrained in professional publishing circles if not the Web more broadly. I expect most of the other requirements and limitations are rarely followed to the letter.
