Help:Licensing

All images uploaded to the wiki should indicate the conditions and/or licenses that govern its use somewhere in the description. Images that cannot be legally used may be removed without warning. The wiki has templates for copyright- and/or license-labeling purposes that are described below. All may be found in Category:File message boxes.


 * No license: Use this if you don't know under which license the file should be. It is highly recommended that you do know under which license the file should be, though.


 * Self: Use this if you created the file content entirely yourself. Basically, this is for fanart and media intended for a specific use in the wiki, i.e. logos.


 * From Wikimedia: Use this if the file came from a WikiMedia project such as Wikipedia.


 * CC-BY-SA: Use this if the file is not from a WikiMedia project but is still licensed under the Creative Commons Attribution-Share Alike License.


 * Other free]: Use this if the file is licensed under a free license other than CC-BY-SA. Be sure to indicate what license it is in the file description.


 * Public domain]: A file is in the public domain if it is not covered by intellectual property rights. This can happen if the rights expire or are forfeited or unclaimed.


 * Fair use: Use this if a file is copyrighted but it is being used in a way that qualifies under fair use under United States fair use laws.


 * Permission: Use this for copyrighted files for which you, the uploader, have permission to use them.
