Carbon gives you control of your featured images:

In post indexes (lists)

It allows you to show featured images in the list of posts, and gives you a number of choices about where your image is shown. You can show images to the left under the headline or show images full column width – either before or after the headline.

In single posts

By default, there is no featured image shown in the post view, but with our included featured image widget you can decide where to show your image (or not to show it at all). The image can be used to show a full width featured image, a featured image that fits into the page width or even show the featured image in the sidebar. The choice is yours.

Using the included widget in conjunction with Jetpack (or any other plugin that gives control over widget visibility) you can decide to display featured images differently on posts and pages or even on a per category basis – complete flexibility.
