In the context of PHP web development, what role does the use of GET parameters play in customizing and controlling the display of images or content on a webpage?

Using GET parameters in PHP allows for dynamic customization and control of the display of images or content on a webpage. By passing parameters through the URL, you can adjust the behavior of your PHP script to display specific images or content based on the values of those parameters. 

<?php
// Check if a specific parameter is set in the URL
if(isset($_GET['image'])) {
    $image = $_GET['image'];
    
    // Display the image based on the parameter value
    echo "<img src='images/$image.jpg' alt='Custom Image'>";
} else {
    // Default image if no parameter is set
    echo "<img src='images/default.jpg' alt='Default Image'>";
}
?>
