What potential issue is the user facing with the random image display in the script?

The potential issue the user is facing with the random image display in the script is that the same image might be displayed multiple times in a row due to the randomness of the selection. To solve this issue, the user can keep track of the last displayed image and ensure that the randomly selected image is different from the previous one. 

<?php
// Array of image file names
$images = ['image1.jpg', 'image2.jpg', 'image3.jpg', 'image4.jpg'];

// Get the last displayed image from session or set to empty string
$lastImage = isset($_SESSION['last_image']) ? $_SESSION['last_image'] : '';

// Get a random image that is different from the last one
do {
    $randomImage = $images[array_rand($images)];
} while ($randomImage == $lastImage);

// Display the random image
echo '<img src="' . $randomImage . '" alt="Random Image">';

// Save the last displayed image in session
$_SESSION['last_image'] = $randomImage;
?>
