I'm attempting to create a "Netvibes"-esque start page for myself with a basic install of Concrete5. This primarily depends on whether I can get thumbnails to show for my displayed feeds--otherwise it'll be a quite boring endeavor.

I've fed some feeds into the RSS displayer, copied from my Netvibes URL's. These are known sources that show images in Pulse, Flipboard, Netvibes, and Google Reader but nothing with the RSS Displayer in Concrete5. The text shows, of course, but no article thumbnails.

Is there a setting that I'm overlooking? Don't see any addons that address this either.
