MediaWiki:UploadFormPermissionHelp

Permission: If the work you want to upload is copyrighted, but you have an explicit permission to license it under a free license, forward any such permission to permissions-commons@wikimedia.org, and place {{subst:PP}} in this field. Otherwise, leave this field blank.

If you know that your file falls under a specialized copyright rule not covered by the licenses mentioned in the "License" drop-down menu below, you may also write a copyright tag directly in this field instead of choosing a license below. If you use a "user license" defined in a subpage of your user page, you must "subst" it. A transclusion of a user license will not be accepted as a license.
