Featured Image

Is there a way I can still have featured images show up with the "Archive Content Layout: Show Full Content" option chosen? I am going with this option because I want to have my "read more" dictate where the link is, rather than a word count. I would also like to have images in my posts appear before the "read more tag" when the above setting is turned on. For some reason the images only appear while on the home page but not on any of the category pages. I really only need these options to work on category pages. Like I said, there seems to be no issue with the home page. Any help would be much appreciated.
