For links to images or other media found on Wikimedia Commons.
Usage
Link to the (highest-level applicable) object-specific category where available, otherwise, a specific image or 3D model. Do not link to more generic categories such as "churches in Birmingham".
Examples
- wikimedia_commons=File:Bicycle crossing, Poland, Kraków, Josepha Conrada.JPG
- wikimedia_commons=Category:St Paul, Birmingham
Wikidata
Where possible, you may also add a wikidata=* tag. Any notable and clearly identifiable material entity is allowed to have a Wikidata entry (See Wikidata's notability guidelines). A Wikidata entity would contain a statement about an image, 3D model, Commons category, or Commons gallery being associated with the entity.
Adding wikimedia_commons=* to an object that has wikidata=* can be considered redundant because Wikidata itself often links to Wikimedia Commons. The vast majority of less experienced (newbies and occasional) users however is way more likely to understand the concept and importance of Wikimedia Commons than Wikidata though and that's why it can be considered good to add both. Even for experienced users, the human-readable value of wikimedia_commons=* is easier to interpret.
Use cases
This can be useful for giving armchair mappers (some of which may be experienced validators) a better chance at understanding the object (a museum, unique house, bridge or memorial for example or even long distance cycle routes e.g. 162016
162016) and eventually complement or correct tags. Especially useful when the object doesn't also have wikipedia=*, wikidata=* or website=* tags or other easily available sources.
Note that these tags are not just intended for internal use! Linked content should therefore be suitable to be shown to end users.

Common tagging mistakes
Automated edits are strongly discouraged unless you really know what you are doing!
- Don't use URLs in values:
- wikimedia_commons=https://commons.wikimedia.org/wiki/File:Isaac_Davis_Monument.jpg#mw-jump-to-license
The value is long, "unreadable" for a human.
Use instead wikimedia_commons=File:Isaac Davis Monument.jpg - wikimedia_commons=https://upload.wikimedia.org/wikipedia/commons/d/d0/Texas_Woman's_University_September_2015_02_(Human_Development_Building).jpg
An application can't find easily the licence, can't choose a better image size, can't display caption ….
Use instead wikimedia_commons=File:Texas Woman's University September 2015 02 (Human Development Building).jpg
- wikimedia_commons=https://commons.wikimedia.org/wiki/File:Isaac_Davis_Monument.jpg#mw-jump-to-license
