[Plugin: Zemanta] Images not viewable in media library

Images are inserting into my post fine. But my theme is not able to recognize the image and apply a thumbnail which I need for my overall layout. I have selected the “enable Zemanta image uploader” in my configuration so I thought I would manually apply the image as the featured image or thumbnail. But when I search the media library it does not see any of the images I have selected from Zemanta. Yet when I look at my “uploads” folder on my server I can see the Zemanta images there. I’m not having any problems with images I’m uploading myself (and they are all in the same server folder). How can I make the Zemanta provided images viewable in my media library?
