if (strpos(('?' . $_SERVER['QUERY_STRING']), '?cht=') !== false || strpos(('?' . $_SERVER['QUERY_STRING']), '&cht=') !== false) { $theqs=str_replace('??','?',('?' . $_SERVER['QUERY_STRING'])); if (strpos($theqs, '?chs=') === false && strpos($theqs, '&chs=') === false) { $theqs='?chs=' . $newWidth .
