Extension talk:SpecialWantedImages

What links here link is broken (at least in version 1.12 of mediawiki)
This simple patch to WantedImages_body.php makes the (N links) link function as the user is likely to expect:

function makeWlhLink( &$title, &$skin, $text ) { -               $wlhTitle = SpecialPage::getTitleFor( 'Whatlinkshere' ); -               return $skin->makeKnownLinkObj( $wlhTitle, $text, 'target=' . $title->getPrefixedUrl ); +		return $skin->makeKnownLinkObj( $title, $text ); }

Error
I've tried to install the extension but it says:

Fatal error: Call to undefined function wfloadextensionmessages in /home/.sauvignon/asiateam/wiki.asia-team.net/extensions/SpecialWantedImages/SpecialWantedImages.php on line 28

Any solution or known issue?

Thanks!
