MaterialProject:Image copyright tags

The MaterialProject takes copyright law very seriously. Image description pages are tagged with the license and the source of the image. This makes it as easy as possible for readers and creators of derivative works to know what they can and can't do with the images in our encyclopedia.

Guidelines

• For an image to be considered "free" under MaterialProject's image use policy, the license must permit both commercial reuse and derivative works.
• MaterialProject (and all Wikimedia projects) strongly prefer "free" images, wherever that is possible. Where no free image exists, it is sometimes permissible to use a non-free (copyright-protected) image under the "fair use" provision. Fair use, in the United States, is the legal right to use copyright-protected materials under certain conditions; MaterialProject has its own conditions that are more restrictive than what is legally permitted.
• All copyright and licensing tags should be put on a line of their own.
• Along with a tag, specify the source or copyright holder information. Provide as much detail as possible.
• If an image is not licensed under a standard license, please specify what the actual license states.
• If you tag an image as requiring attribution, please specify who needs to be attributed.
• If multiple categories apply to an image, add all that apply.
