Once you have your images added to the Media Library, you can define a standard WordPress gallery that includes the images you want in the slide show.
The first step for this is to create a new Weaver Slider Posts post that will include the gallery. Open the Dashboard Slider Posts : New Slider Post page. Show Sliders includes this new custom post type to make it easy to define posts to specify which images to include. You can use a meaningful title for this Show Post. For example, you could call it “Colorado”. You will use the title slug in Step 3., so don’t make it too long.
Don’t close the post editor page yet.
