Free use image sources that allow commercial use

If any post links here as the source of an image, it means that the image is free to use: no royalties, no copyright, even for commercial use. These images are usually licensed under the Creative Commons Zero(CC0) license, the Wikimedia Commons licenses or another similar license.

Common sources for CC0 images are Pexels and Pixabay. Common sources for images that are accepted as Wikimedia Commons are images found on websites such as Wikipedia, Wiktionary and other similar sites.

If an image is linked here and is NOT free to use for commercial purposes, please leave a comment below and the attribution shall be revised by me, and if the link is not mine, I shall try to contact the author to desist the attributions, and will contact every possible blacklist owner to flag such user until the end of times unless they accept the cease and desist request.

If any image source claim is linked to here from any post or comment, it shall be taken for granted that the author of the hyperlink claims that the image in question is explicitly designated as a free use image for commercial purposes.

I beg the reader to understand that the effort of researching the specific source of an image explicitly designed as free use for commercial purposes is wasted as these licenses permit any and all unattributed use of the resources.
