Bing Image Search uses a copyright filter based on the Creative Commons licensing system. The results that are returned are images that have been tagged with Creative Commons licenses. A link to the source of the image is provided, which you should use to review the source of the image and the applicable license to determine whether your use will comply with the license. (The settings can be switched to show all web results to view more images.) However, you are responsible for respecting others’ rights, including copyright. Learn more here.

If you mean an image from the internet or something, you can just save it to your computer and basically follow the rest of the steps above.
Be careful: most Creative Commons images require attribution, meaning you need to give credit to the artist in order to use the image.
