How can I modify this ET theme?

Hi,I am using the Nova theme design by Elegant Themes.

They have what’s called a featured slider:

I would like to display an image that fills the width of this slider. And still have it link off to other pages.

Example of how it currently displays them:

Example of how I would like it displayed:

Here are the only settings they provide:

As you can see there isn’t a display image only option.
Here is a site that appears to achieved this result:

And here is my current thread on Elegant themes support forum:

I really need this option, please if anyone can help me I would greatly appreciated it.
