Details

Point the "Upload file" link in the sidebar "Tools" section to a custom URL. Useful if you want to direct users to a shared repository by default without disabling local uploads, e.g.:

$wgUploadNavigationUrl = '//commons.wikimedia.org/wiki/Special:Upload';

If you wish to point users to a custom upload page on the wiki, use an appropriate relative URL:

$wgUploadNavigationUrl = '/wiki/Project:Upload_start_page';

If $wgUploadNavigationUrl is set to false, then a link to Special:Upload is added to the toolbar if uploads are enabled and the user has both upload and edit permissions. If $wgUploadNavigationUrl is set to a url, the link is always shown, regardless of the user's permissions.

Red file links

As of r69997 $wgUploadMissingFileUrl is used for red links. This allows pointing $wgUploadNavigationUrl to an external page that is not per se a Special:Upload directly. If $wgUploadMissingFileUrl is not defined, then $wgUploadNavigationUrl will be used as a fallback since 1.19.
