What are the key differences between using imageJPEG() and Header() to display images in PHP?

The key difference between using imageJPEG() and Header() to display images in PHP is that imageJPEG() is a function specifically designed for creating JPEG images and outputting them directly to the browser, while Header() is a general function used for setting HTTP headers, including content-type headers for images. If you want to display a JPEG image directly in the browser, imageJPEG() is the preferred method as it handles the image creation and outputting automatically. 

// Using imageJPEG() to display a JPEG image
header('Content-Type: image/jpeg');
$image = imagecreatefromjpeg('image.jpg');
imagejpeg($image);
imagedestroy($image);
