Adding an Image in a Blog Carousel Element in Visual Composer

How do i add a featured image to a blog carousel element when using visual composer, or is there another way to show my specific blog Category, and features image with an expert from the posts?

Right now on the BLOG CAROUSEL element you can make the element show the post title and an excert, but the image does not show……THANKS!! IS there another element that we can use to do this thats not titled BLOG ELEMENT, or can we add some code to the advanced tab on the BLOG CAROUSEL element to achieve this? THANKS!!!!
