Multiple Random Images on same page

[AndersonMM]

I'm trying to put 3 different random images on the same page. In my template, I just put:

PHP Code:

<?php random_content('Square-Images'); ?>
<?php random_content('Square-Images'); ?>
<?php random_content('Square-Images'); ?>

But this causes occasional duplicate images. Is there a way to achieve this so there are 3 unique random images on the page every time?

Thank you.
