gd troubles as usual

[AN-net]

ok well im trying to modify the fetch_avatar_url function so it will place text over a user's avatar but of course it isnt workin

here is the code:

PHP Code:

            if ($vboptions['usefileavatar'])
            {
                $preavaurl= "http://www.animationation.net/community/$vboptions[avatarurl]/avatar{$userid}_{$avatarinfo[avatarrevision]}.gif";
                $preava= ImageCreateFromGif($preavaurl);
                $colortext= imagecolorallocate($preava, 0, 0, 0);
                ImageTTFText($preava, 6, 0, 1, 1, $colortext, "./arial.ttf", "BANNED!");
                return "$vboptions[avatarurl]/avatar{$userid}_{$avatarinfo[avatarrevision]}.gif";
            }
            else
            {
                return "image.php?u=$userid&dateline=$avatarinfo[dateline]";
            } 


see the problem is its still showing the original avatar unedited, how can i achieve this?
