How can the PHP function mime_content_type be used to improve image loading functionality?

When loading images in a web application, it's important to ensure that the correct MIME type is set for each image to prevent any potential security vulnerabilities or issues with browser compatibility. Using the PHP function mime_content_type can help improve image loading functionality by dynamically determining the MIME type of an image file and setting it accordingly when serving the image to the client. 

$imagePath = 'path/to/image.jpg';
$mime = mime_content_type($imagePath);
header('Content-Type: ' . $mime);
readfile($imagePath);
