How can the issue of the image not automatically reloading on the web be addressed when using PHP for text on images?

Issue: The problem of the image not automatically reloading on the web when using PHP for text on images can be addressed by setting appropriate cache-control headers in the PHP script. By sending the correct headers, we can instruct the browser to reload the image from the server each time it is requested, preventing it from being cached. PHP Code Snippet: 

<?php
header("Cache-Control: no-cache, must-revalidate");
header("Expires: Sat, 26 Jul 1997 05:00:00 GMT");
header("Content-type: image/png");

// Code to generate or load the image with text
$image = imagecreatefrompng("image.png");

// Code to add text to the image
$textColor = imagecolorallocate($image, 255, 255, 255);
imagettftext($image, 20, 0, 10, 30, $textColor, "arial.ttf", "Hello World");

// Output the image
imagepng($image);
imagedestroy($image);
?>
