In what scenarios would it be more appropriate to use JavaScript instead of PHP to dynamically change images on a website based on certain conditions?

When you need to dynamically change images on a website based on user interactions or real-time events without reloading the page, it is more appropriate to use JavaScript. JavaScript can handle client-side interactions efficiently, allowing for seamless image changes without the need for server requests. PHP, on the other hand, is better suited for server-side processing and generating dynamic content before the page is loaded. 

// PHP code example
// This PHP code snippet demonstrates how to dynamically change images on a website based on certain conditions using JavaScript

<?php
// Define the condition that determines which image to display
$condition = true;

// Output the JavaScript code that dynamically changes the image based on the condition
echo '<script>';
echo 'if (' . $condition . ') {';
echo 'document.getElementById("image").src = "new_image.jpg";';
echo '} else {';
echo 'document.getElementById("image").src = "default_image.jpg";';
echo '}';
echo '</script>';
?>

<!-- HTML code to display the image -->
<img id="image" src="default_image.jpg" alt="Image">
