To automatically change a background image every 10 minutes without the need for a file or database, you can use PHP along with a predefined list of background images. By utilizing the time functions in PHP, you can dynamically select a new background image every 10 minutes based on the current time. 

<?php
$backgrounds = ['image1.jpg', 'image2.jpg', 'image3.jpg']; // List of background images
$index = intval(date('i')) % count($backgrounds); // Calculate index based on current minute
$bgImage = $backgrounds[$index]; // Select background image based on index

echo '<style>body { background-image: url("' . $bgImage . '"); }</style>'; // Output CSS to change background image
?>
