How can PHP headers be utilized to output an image as a response to an HTML img tag?

To output an image as a response to an HTML img tag using PHP headers, you can set the content-type header to "image/jpeg" (or the appropriate image type) and then use readfile() to output the image file. This will allow the image to be displayed in the HTML img tag. 

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

// Output the image file using readfile
readfile('path/to/image.jpg');
?>
