If I had a stock photo site that contained a mix of free Creative Commons licensed photos and commercial stock photos (where I make a commission), would I be allowed to include photos licensed under CC BY-NC-ND 4.0?
I know BY-NC-ND prohibits commercial use or derivative works, but I'm not clear on what the "boundary" is. If I'm not making money directly off the BY-NC-ND photos, but they are part of a larger web site which does make money, is that considered commercial use? Or if I show a list of related photos under a BY-NC-ND photo, is that web page a derivative work?
