How can PHP headers be used to properly display images generated from binary data within a web page?

When displaying images generated from binary data within a web page using PHP, you need to set the correct Content-Type header to indicate that the response contains an image. This can be achieved by using the header() function in PHP to set the Content-Type to the appropriate image format (e.g., image/jpeg, image/png). Additionally, you need to output the binary image data using the appropriate encoding (e.g., base64_encode) to ensure it is rendered correctly in the browser. 

<?php
// Assume $binaryImageData contains the binary image data

// Set the Content-Type header to indicate that the response contains an image
header('Content-Type: image/jpeg');

// Output the binary image data using base64 encoding
echo base64_encode($binaryImageData);
?>
