GD resize and text

Noriu pakeisti paveiksliuko dydi (800x600) sitas dalykas suveikia..

Toliau bandant uzrasyti texta nelabai kas ir gaunas :)

Gal kas gali uzvesti ant kelio ?

<?php
//header ("Content-type: image/jpg") ;
$foto = $_GET['foto'];
$imagename = "$foto";
list($width, $height) = getimagesize($imagename);
$newwidth = 800;
$newheight = 600;
// Load
$thumb = imagecreatetruecolor($newwidth, $newheight);
$source = imagecreatefromjpeg($imagename);
// Resize
imagecopyresized($thumb, $source, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
// Output
$text = "Test Text";
$size = "30";
$angle = "0";
$x = "50";
$y = "12";
$black = imagecolorallocate ($img, 0, 0, 0);
imagettftext ($thumb, $size, $angle, $x, $y, "0", "arial.ttf", $text);
$sumazintas = imagejpeg($thumb);
?>
