== Modification ==
This function depends on an added extension, the following code is saved as a php file named '''<code>YouTubeTag.php</code>''' in the extensions folder and '''<code>require_once('extensions/YouTubeTag.php');</code>''' is added to [[LocalSettings.php]]. Note that this code is a slight modification of the [http://www.mediawiki.org/wiki/Extension:YouTubeTag original] in that it allows the width to be specified.
