Wordpress random thumbnail SIZE?

Question

I'm getting a thumbnail like this in Wordpress:

<?php echo get_the_post_thumbnail($page->ID, 'thumbnail'); ?>

Now there is 'thumbnail' size but also 'medium', 'large' and 'full'.

How do I get the php code to display these size random? So sometimes there 'small' then 'thumbnail' and then 'full'.

Answer 1

Haven't tested, but something like this should work (assuming I've understood your question):

<?php
$sizes = array('thumbnail', 'medium', 'large', 'full');
$index = array_rand($sizes);
echo get_the_post_thumbnail($page->ID, $sizes[$index]);
?>
