The next step is creating/editing slides. You get there by just clicking on “Edit Slides” in the Slider Form window.
Just press “New Slide” and the native WP Media Upload dialog window will appear. Choose or Upload the slide’s background image, choose “Full Size” and then “Insert Into Post” (all like you are used to it in your WP editor). You can always click on the pic to change it.
Use the arrow handles on the right side to change the slides position in the slider (top to bottom = first to last slide to be shown) or delete it with the “Delete” button.
The “Edit Slide” leads you to the next chapter “Slide”.
