What best practices should be followed when outputting images in PHP for HTML display?

When outputting images in PHP for HTML display, it is best practice to set the correct Content-Type header to ensure the browser interprets the data correctly. Additionally, it is important to encode the image data using base64 encoding to embed the image directly into the HTML. This approach helps improve performance and reduces the number of HTTP requests made by the browser. 

<?php
// Path to the image file
$imagePath = 'path/to/image.jpg';

// Get the image data
$imageData = file_get_contents($imagePath);

// Convert the image data to base64
$base64Image = base64_encode($imageData);

// Output the image in HTML
echo '<img src="data:image/jpeg;base64,' . $base64Image . '" />';
?>
