Hi, I found this but when I test it I see only a black image?

<?php

// show the correct header for the image type
header("Content-type: image/jpg");

// an email address in a string
$string = "email@example.com";

// some variables to set
$font = 4;
$width = ImageFontWidth($font) * strlen($string);
$height = ImageFontHeight($font);

// lets begin by creating an image
$im = @imagecreatetruecolor ($width,$height);

//white background
$background_color = imagecolorallocate ($im, 255, 255, 255);

//black text
$text_color = imagecolorallocate ($im, 0, 0, 0);

// put it all together
imagestring ($im, $font, 0, 0, $string, $text_color);

// and display
imagejpeg ($im);
?>
