Licensing

Slate doesn’t own the images it shows and doesn’t license them. Each image comes from a source, and that source’s license decides what you may do with it. The image’s preview names its source and photographer.

Pexels images

Pexels images are under the Pexels License. In short:

• free to use, for personal and commercial projects;
• attribution is not required, though photographers appreciate it;
• you may modify them.

Not allowed under that license, among other things: selling unaltered copies, implying endorsement by people in a photo, or redistributing the images as a competing stock library. Read the full license before relying on it.

NASA images

Images from NASA’s library are generally not copyrighted in the United States, and NASA allows wide use — including commercial — under its media usage guidelines. Some conditions apply: you may not use the NASA insignia or logos, or imply NASA endorses you, and images that show identifiable people or that NASA credits to a third party can carry their own restrictions.

Good practice

• Credit when you can: “Photo by name on Pexels”, or “Image: NASA”.
• Check people and trademarks in an image before using it in advertising.
• If an image’s license matters to you, open it at its source and read the terms there.

If you think an image on Slate shouldn’t be there, email [email protected] with its address.
