Can I sell Unsplash photos?

Legally, the CC0 license allows you to sell the photos posted on Unsplash. However, the Creative Commons and Unsplash communities are pretty vocal in their dislike for this (not to mention it makes no economic sense, since the photo is already free).

We recommend never selling another photographer’s work without adding to it creatively, through remixing or other methods. A simple way to think about this is to ask yourself: did I add something to this in a way that deserves value? If I were the original photographer, would I see this as a creative use of my photo?

Made with Unsplash has many examples of remixes created with Unsplash photos that showcases how the photos can be used creatively.
