How to add text to an image with PHP GD library

I have image creation code in image_creator.

<?php
header("Content-Type: image/jpeg");
$im = ImageCreateFromGif("photo.gif"); 
$black = ImageColorAllocate($im, 255, 255, 255);
$start_x = 10;
$start_y = 20;
Imagettftext($im, 12, 0, $start_x, $start_y, $black, 'verdana.ttf', "text to write");
Imagejpeg($im, '', 100);
ImageDestroy($im);
?>

JavaScript
​x
 
<?phpheader("Content-Type: image/jpeg");$im = ImageCreateFromGif("photo.gif"); $black = ImageColorAllocate($im, 255, 255, 255);$start_x = 10;$start_y = 20;Imagettftext($im, 12, 0, $start_x, $start_y, $black, 'verdana.ttf', "text to write");Imagejpeg($im, '', 100);ImageDestroy($im);?> ​

The file for image output is image.php and has below code

<html>
<head>
</head>
<body>
    <img src="http://localhost/image_creator.php"/> 
</body>

</html>

JavaScript
 
<html><head></head><body>    <img src="http://localhost/image_creator.php"/> </body>​</html>​

When I run image.php, I just get a blank page. Why is it so?

Use this to add text to image (copied from PHP for Kids)

<?php
//Set the Content Type
header('Content-type: image/jpeg');

// Create Image From Existing File
$jpg_image = imagecreatefromjpeg('sunset.jpg');

// Allocate A Color For The Text
$white = imagecolorallocate($jpg_image, 255, 255, 255);

// Set Path to Font File
$font_path = 'font.TTF';

// Set Text to Be Printed On Image
$text = "This is a sunset!";

// Print Text On Image
imagettftext($jpg_image, 25, 0, 75, 300, $white, $font_path, $text);

// Send Image to Browser
imagejpeg($jpg_image);

// Clear Memory
imagedestroy($jpg_image);
?>

JavaScript
 
<?php//Set the Content Typeheader('Content-type: image/jpeg');​// Create Image From Existing File$jpg_image = imagecreatefromjpeg('sunset.jpg');​// Allocate A Color For The Text$white = imagecolorallocate($jpg_image, 255, 255, 255);​// Set Path to Font File$font_path = 'font.TTF';​// Set Text to Be Printed On Image$text = "This is a sunset!";​// Print Text On Imageimagettftext($jpg_image, 25, 0, 75, 300, $white, $font_path, $text);​// Send Image to Browserimagejpeg($jpg_image);​// Clear Memoryimagedestroy($jpg_image);?>​
