Featured Image from Post isn’t showing

I have a valid feed, but only the default image is showing when I embed it on a page using Feedzy.

Here is my feed:
http://santaclaritaarts.com/category/current-exhibitions+the-main/feed/

Here is the page I’m embedding it on:
http://atthemain.org/_test/

Here is my shortcode:
[feedzy-rss feeds=”http://santaclaritaarts.com/category/current-exhibitions+the-main/feed/” max=”1″ feed_title=”no” meta=”no” summary=”yes” summarylength=”1000″ thumb=”yes” default=”” size=”250″]

The post that’s in the feed has a Featured Image set, although there are no images in the post itself.
