Fair use rationale

 * Officially released by the 2008 Beijing Olympics committee to give visual representation of the medals for press release and the world
 * Relatively hard to replace since all three medals are presented at once.
 * Only used for coeducational and good will reasons on Wikipedia to complement the article
 * Until free source is provided I assume it is fair use to use this on Wikipedia
 * This image is used by non-profit organization, Wikimedia Foundation to complement the 2008 Summer Olympics that it represents
 * This image is of unique nature since all three medals are hard to photograph unless it is officially illustrated by the organization or the person(s) who won all three distinct medals combine them on one photo shoot. In that case it will need to have happen after the Olympics and willingness of the person to share the image.
 * The closeup view of these medals are necessary to look at its design.
