The first thing you need to is create a post with a picture in it. Then on the right side down toward the bottom of the post page you will see in blue, “Featured Image” Put the Image you want to show up on the slider there.
Then go to to Appearance -> Theme Options and at the top of the page you will see tabs. Click on the second tab called “Featured Post Slider.” Then click “Featured Post Slider Options.” You have to enter the post ID which you find on the “All Posts” page just to the left of the post title.
I’m new at this, so this may not be the best way to do it, but it worked at least for one post for me.
