Find

            $post['sig'] = postify($post['sig'], 'no', 'no', $forum['allowsmilies'], $SETTINGS['sightml'], $SETTINGS['sigbbcode'], $forum['allowimgcode'], false);


Add code above

            // Make sure users can't post more than one image in a signature.
            $findimg = stripos($post['sig'], '[img');
            if ($findimg !== FALSE) {
                $findimg++;
                $sig1 = substr($post['sig'], 0, $findimg);
                $sig2 = substr($post['sig'], $findimg);
                $post['sig'] = $sig1 . str_ireplace('[img', '[ img', $sig2);
            }

This step needs to be repeated 3 times.  Do add the new code for all 3 instances.
