How does the use of image headers impact the generation and display of PNG images in PHP?

When using image headers in PHP, it is important to set the correct content type header for PNG images to ensure proper generation and display. This can be done by setting the header to "Content-Type: image/png" before outputting the image data. Failure to set the correct content type header may result in the image not being displayed correctly in the browser. 

<?php
// Set the content type header for PNG images
header('Content-Type: image/png');

// Generate or load your PNG image data here
$imageData = file_get_contents('image.png');

// Output the image data
echo $imageData;
