trying to make featured image show

HI,
I'm using the following plugin:
https://wordpress.org/plugins/featured-images-for-categories/

I'm trying to show the featured image on every category page to the left of the description. So for example on this page:
http://www.homefrontmagazine.com/category/feature/

I would like the featured image to be to the left of the left of the text that says featured article and the description.
