We don't have to write original rule of copyright. We just follow the rule of Fandom. So we should describe the copyright. But as @Denis says, many pictures which do not have description of copyright. What we can do is


 * Describe copyright if we can guess. For example, screenshot of Fandom page is CC.
 * If the user who uploaded the image is active, we can ask the user about the copyright.
 * If it is a mathematical equation, we can keep it because mathematical equation is not copyrighted.
 * If it is picture which appears to have copied from somewhere, we could delete it.
