You can use some code like this in your block's view.php file:

<?php    
   // Get repeating items
   $items = $controller->getRepeatingItems();
   // Randomize the items
   shuffle($items);
   // Display image from first item from the randomized array
   $items[0]->image->display();
?>

(This code assumes the handle of your image field is `image`... change the last line of code accordingly though if the field has a different handle.)

Note that if you have block caching enabled in your dashboard, it will cache the randomly-chosen image and keep re-displaying it until the cache is cleared. If this is a problem for you, there is a workaround -- let me know what the block handle you are using is and I can then give you specific instructions on how to do this.

Thanks,
Jordan
