Are there alternative technologies, such as Flash, that can be used to display random images besides JavaScript?
To display random images without using JavaScript, you can utilize PHP to generate a random number and then use that number to select an image to display. This can be achieved by storing the image file names in an array and using the random number as an index to select one of the images.
<?php
// Array of image file names
$images = ['image1.jpg', 'image2.jpg', 'image3.jpg', 'image4.jpg'];
// Generate a random number between 0 and the total number of images
$randomIndex = rand(0, count($images) - 1);
// Get the random image file name
$randomImage = $images[$randomIndex];
// Display the random image
echo '<img src="' . $randomImage . '" alt="Random Image">';
?>
