API Code for Cover Image not working

Per the instructions on this doc:
http://stackideas.com/docs/easysocial/developers/users/users

I have tried embedding the cover image... while the same code works for name, followers etc it is not working for cover image.

For example I use this code to embed the user page name:

<?php $userId = JFactory::getApplication()->input->getInt('user_id');

$my     = Foundry::user();

echo $my->getName(); ?>

The key part of that code as you mention in the api doc is :

$my     = Foundry::user();

echo $my->getName(); ?>

Which works successfully HOWEVER when I use the same code as instructed from your API for cover image.

$my     = Foundry::user();

echo $my->getCover()->getSource( 'large' );?>

It messes up my site... see my screenshot;

So something is not quite right... please advise.. thanks!
