What are the best practices for handling image output in PHP to ensure proper rendering and display in web applications like Joomla?

When handling image output in PHP for web applications like Joomla, it is important to set the correct headers to ensure proper rendering and display of the image. This includes setting the Content-Type header to the appropriate image type (e.g. image/jpeg, image/png) and outputting the image data using functions like imagejpeg() or imagepng(). 

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

// Output the image data
$image = imagecreatefromjpeg('path/to/image.jpg');
imagejpeg($image);
imagedestroy($image);
