Creative Commons is a non-profit organization that provides free licenses to anyone who wants a safe way to share their creativity and knowledge with the world. A Creative Commons license is not designed to replace a creator’s copyright, but to help them quickly, easily, and legally change the terms and conditions of their copyright so that others can safely use their content under approved conditions.
There are six Creative Commons licences. Each licence confers a set of baseline rights on licensees (e.g., as to copying, use and distribution) and a set of baseline obligations and restrictions (e.g., licensees cannot sublicense the licensed work and they must not falsely attribute the work to someone else). All of the licences also contain one or more “licence elements”. There are four Creative Commons licence elements: Attribution, NonCommercial, NoDerivatives and ShareAlike. The Attribution element is common to all of the licences. The other three elements are used in different combinations across five out of the six licences.
I have decided the work on my WordPress licensing under the following terms:
This work is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License.
Here are several plugins that have huge databases of creative commons images for WordPress users to pick from:
1. Only Image
4. Image Inject
This is a WordPress plugin that allows users to easily insert photos and images into their WordPress posts. Search among many thousands of free creative commons images for any keywords of your choice, then pick the best of them for the article you are working on and insert them into your post or set them as featured image. Supported image sources are Flickr and Pixabay.
