English: Screenshot at 0:19 of video of U.S President Obama with YouTube video content creator Iman Crosson. Screenshot is essentially the video's "thumbnail" view as used by the whitehouse.gov website.
Attribution information, such as the author's name, e-mail, website, or signature, that was once visible in the image itself has been moved into the image metadata and/or image description page. This makes the image easier to reuse and more language-neutral, and makes the text easier to process and search for. Commons discourages placing visible author information in images.
