What is the significance of setting the Content-Type header to "image/png" in the context of image manipulation in PHP?

Setting the Content-Type header to "image/png" is significant because it informs the browser that the response contains a PNG image. This is crucial for proper rendering of the image on the client side. Without setting the correct Content-Type header, the browser may not interpret the response correctly and display the image improperly or not at all. 

<?php
// Set the Content-Type header to inform the browser that the response contains a PNG image
header('Content-Type: image/png');

// Your image manipulation code here

// Output the image
imagepng($image);
imagedestroy($image);
?>
