How can the code be optimized to ensure only one icon is displayed for navigating between images?

To ensure only one icon is displayed for navigating between images, we can modify the code to check if there are multiple images before displaying the navigation icon. This can be achieved by checking the count of images in the array and only displaying the icon if there is more than one image available. 

<?php
// Check if there are multiple images before displaying navigation icon
if (count($images) > 1) {
    echo '<div class="navigation-icon">Navigate between images</div>';
}
?>
