   I'm using a showcase theme which uses custom fields to display post images. I'd like these images and a link to the original site to be displayed in my feed. The relevant fields are "Thumbnail Full" and "URI". The following modified plugin which I found on another support topic - http://wordpress.org/support/topic/99432?replies=5 - works, but I don't know how to edit it to make it show:

   • the thumbnail image itself instead of the link text
   • the URI as a link

   Can anyone help with this?
