How can the user modify the script to ensure that only existing image files within the specified range are displayed randomly?

To ensure that only existing image files within the specified range are displayed randomly, the user can modify the script by first generating a list of existing image files within the specified range and then selecting a random image from that list for display. This can be achieved by using the glob() function to get a list of image files and then using array_rand() to select a random file from the list. 

<?php
$min_range = 1;
$max_range = 10;

$image_files = glob("images/*.jpg");
$existing_files = array_filter($image_files, function($file) {
    return is_file($file);
});

if (!empty($existing_files)) {
    $random_image = $existing_files[array_rand($existing_files)];
    echo '<img src="'.$random_image.'" alt="Random Image">';
} else {
    echo 'No image files found within the specified range.';
}
?>
