The pre-filled content[1] seems to come from wpUploadDescription (found via examining page-source) which is mentioned at https://www.mediawiki.org/wiki/Manual:Parameters_to_Special:Upload Does that help?

There are certain messages you can use, such as [[MediaWiki:filehist-help]], [[mediawiki:metadata-help]], but they aren't really in ideal position. On commons, there is some user js that is sort of for this purpose: https://commons.wikimedia.org/wiki/MediaWiki:Gadget-Stockphoto.js (and associated .css) which adds a "Use this file on a wiki" button with examples. Similarlly I think the MediaViewer extension also has a button for examples. If you're up for making your own extension, Check out the 'ImagePageAfterImageLinks' hook. e.g. Something along the lines of $wgHooks['ImagePageAfterImageLinks'][] = function ( $page, &$html ) { $html .= wfMessage( 'image-page-extra-stuff' )->inContentLanguage()->parse(); }; Untested, but in theory, placing that in LocalSettings.php would add a new message named [[MediaWiki:image-page-extra-stuff]] to every file page. -- bawolff On Sat, Aug 6, 2016 at 4:42 PM, Emanuele D'Arrigo <manu3d(a)gmail.com> wrote:
