What is the potential impact of removing the header("Content-type: image/png") when outputting a PNG image in PHP?

Removing the header("Content-type: image/png") when outputting a PNG image in PHP can result in the image not being displayed correctly in the browser. This header specifies the type of content being sent to the browser, so without it, the browser may not recognize the content as an image and display it improperly. To fix this issue, make sure to include the header specifying the content type before outputting the image data. 

<?php

// Set the content type header to specify that the output is a PNG image
header("Content-type: image/png");

// Output the PNG image data
$imageData = file_get_contents("image.png");
echo $imageData;

?>
