What are the best practices for implementing dynamic image changes on a webpage using PHP?

When implementing dynamic image changes on a webpage using PHP, it is important to ensure that the images are properly updated based on user interactions or other triggers. One common approach is to use PHP to dynamically generate the image URLs based on certain conditions or data from a database. This can be achieved by using PHP to dynamically output the image source attribute in the HTML markup. 

<?php
// Retrieve image file path from database or other data source
$imagePath = "images/image1.jpg";

// Output the image tag with the dynamic image source
echo '<img src="' . $imagePath . '" alt="Dynamic Image">';
?>
