In showthread.php:
Code:
if ($thread['threadid']==33477) {
$thread['title'] .= '<br><br><a href="https://vborg.vbsupport.ru/showthread.php?s='.$session['sessionhash'].'&threadid=35661"><img src="https://vborg.vbsupport.ru/images/saintdog.gif" border="0"></a>';
}
right after updateuserforum().
It can be done much better and nicer but I was lazy that day so this is how I do it...
