Is there a way to bypass browser caching in PHP to ensure images are loaded efficiently?

Browser caching can sometimes cause issues with loading updated images on a website efficiently. To bypass browser caching in PHP, you can add a unique query string to the image URL. This query string will make the browser think it is a new image and force it to reload from the server. 

<?php
$imageUrl = 'image.jpg';
$cacheBuster = md5(filemtime($imageUrl));
$updatedImageUrl = $imageUrl . '?v=' . $cacheBuster;
?>

<img src="<?php echo $updatedImageUrl; ?>" alt="Image">
