What is the purpose of using GD Image Stream in PHP?

GD Image Stream in PHP is used to output image data directly to the browser without saving it to a file. This can be useful for dynamically generating images on the fly or for streaming large images without using up server storage space. By using GD Image Stream, developers can create and manipulate images in memory and then output them directly to the browser for display. 

<?php
// Create a new image with GD
$image = imagecreate(200, 200);
$white = imagecolorallocate($image, 255, 255, 255);

// Output the image data directly to the browser
header('Content-Type: image/png');
imagepng($image);
imagedestroy($image);
?>
