Adding Pinterest pulls incorrect image

Trying to help one of my subdomain owners set up Floating Social. Using the directions here, I added this code:

<a href="http://pinterest.com/pin/create/button/" class="pin-it-button" count-layout="vertical">Pin It</a>
<script type="text/javascript" src="http://assets.pinterest.com/js/pinit.js"></script>

Even though it indicates the vertical layout, the plugin pulls the horizontal. (I can add an image when someone responds. Unfortunately, I can't add an image once I've submitted a question, nor can I add another comment unless/until someone else responds. (Weird.))

P.S. I have it set to show up on all pages, but when it gets to a page or post that uses Twitter Facebook Social Share -- it no longer appears. ???
