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.

$wgAllowCopyUploads = true

$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;
