T146666 creates a Commons extension moving files there, given a url. This task is about providing a link in Wikipedia to move files.
Add a link "Move to Commons" to the tab bar, where appropriate.
The link is appropriate, when
- the page is a "real" wikipedia file page, i.e. the page of an image that is really just on Wikipedia, not on Commons
- the user is at least autoconfirmed - TODO: should it be allowed for less people? Moving pages is something that is only allowed for admins. Maybe we need a moving-a-file right that allows the moving to Commons, and could be added e.g. to the admin group (if we decide for such a right, please reconsider T143414)
When the link is clicked, the file is moved to Commons with the Commons extension of T146666, and the user is redirected to the new file page on Commons.
This task does not include any special handling for specific licences.
