eheheh ... what a trick ! do you want some more cofee ?
thanx for spending time on that...

here is a new sample :
php:
<?
Header("Content-type: image/png");
$w = 44;
$h = 96;
$im = imagecreate($w, $h);
$red = imagecolorallocate($im, 255, 0, 0);
imagettftext ($im, 2, 0, 0, $h/2, $red, "./arial.ttf", "test");
imagePNG($im);
imageDestroy($im);
?>
hard to do less...
