How can the rand function be properly implemented in PHP for random image selection?

To properly implement the rand function in PHP for random image selection, you can create an array containing the file paths of the images you want to choose from. Then, use the rand function to generate a random index within the range of the array length and use that index to select the image file path. 

<?php
// Array of image file paths
$images = array("image1.jpg", "image2.jpg", "image3.jpg", "image4.jpg");

// Get a random index
$randomIndex = rand(0, count($images) - 1);

// Select the random image
$randomImage = $images[$randomIndex];

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