What are common reasons for dynamic images not updating despite changes in the database in PHP?

One common reason for dynamic images not updating despite changes in the database in PHP is caching. The browser or server may be caching the image, preventing it from being refreshed. To solve this issue, you can add a cache-busting parameter to the image URL, forcing the browser to fetch the updated image from the server. 

<?php
$imageUrl = 'image.jpg';
$imageUrl .= '?timestamp=' . time(); // Add a cache-busting parameter

echo '<img src="' . $imageUrl . '" alt="Dynamic Image">';
?>
