This feature also helps artists who want their images to be discovered and reused across the web — on their own terms. Creative Commons licenses allow artists to specify the ways others may use their work. Artists can license their images for general reuse, or for noncommercial reuse only. They can also decide whether or not to grant people the right to modify or remix their images. Once they've chosen to make their work available online under these terms, Google Images helps people start to find and use it.
To enable this feature, go to our advanced image search page. Under the "Usage rights" section, you can select the type of license you'd like to search for, such as those marked for reuse or even for commercial reuse with modification. Your results will be restricted to images marked with CC or other licenses. Once you confirm the license of the image and make sure that your use will comply with the terms of the license (such as proper attribution to the image's owner), you can reuse the image. Some of you may already see these options, and we'll be rolling this feature out to everyone throughout the day.
There's some fine print, of course. This feature identifies images that are tagged with licenses that authorize reuse. You'll still have to verify that the licensing information is accurate. We can help you take the first step towards finding these images, but we can't guarantee that the content we linked to is actually in the public domain, or available under the license.
We believe that we've made it easier for people to find images they can use while helping artists who've made their images available under these licenses to gain exposure for their work. So try it out, and let us know what you think.
