I have a K2 Category that I want in a feed. How do I set the RSS feed descriptions and images.

It is automatically generated. The images are the items K2 images and the descriptions are the item's introtexts.
Finally the feed's description is the category's description.

I assumed that was the case, but as you can see below

It's displaying the wrong information. Using the Feed Display that comes with Joomla for the administrator section.. The category image isn't showing either.

And what's with the extra Site names?

Is there a link to the feed?

To the actual source of the feed?
www.webhelpus.com/specials

Yes.
The images are pulled form the items.
Since you only have one time with no image, there are no images.

As for the description. Did you change the menu items's description and the feed did not update?
