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.
