Default feed category image not posting

Hi,

I assume that the default feed category image is supposed to be added for any feed posts that contain no featured or other images. I added the full url to for a default image (http://www.popfix.net/wp/wp-content/default-pics/tmz.png), under the default categories tab, however the default image doeds not appear in the post (using feed to post). Any help would be greatly appreciated.
