Creative Commons licenses provide a flexible range of protections and freedoms for authors, artists, and educators.
I have clients and friends using images from Google and Bing search for their websites and other online platforms. Few know about copyrighted laws or how to determine whether they can use an image or not.
The Creative Commons website is your one-stop to learn about licenses, copyrights, public domain, and more. Don't get embroiled in a lawsuit because 'you didn't know.' 'You didn't know' rarely wins as a defense.
