To upload images, you should ensure that:

   * The 'images' directory is writable
   * Upload in MediaWiki is enabled. To do this, you should set $wgEnableUploads in LocalSettings.php to true
   * The file type you wish to upload must be allowed in /includes/DefaultSettings.php:

     $wgFileExtensions = array( 'png', 'gif', 'jpg', 'jpeg', 'doc', 'xls', 'pdf' );

You can also set

$wgStrictFileExtensions = false;

to allow most file types to be uploaded.

   * The user is logged in

     $wgGroupPermissions['user']['upload'] = false;
   * To create a special group called "uploadaccess", and allow members of this group to upload files, you should set:

     $wgGroupPermissions['uploadaccess']['upload'] = true;
   * To allow "autoconfirmed" (non-newbie) users to upload files, you should set:

     $wgGroupPermissions['autoconfirmed']['upload'] = true;
