What are some best practices for handling headers and content types in PHP scripts to ensure proper image display?

When displaying images in PHP scripts, it is important to set the appropriate headers and content types to ensure proper display in the browser. This can be done by using the header() function in PHP to specify the content type as image/jpeg, image/png, etc. Additionally, it is recommended to use the readfile() function to output the image content. 

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

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