The slider shows featured images of posts/pages. Click on “Set featured image! => “Upload” => Pick image => Use as featured image” on the post/page editor page (right sidebar near the publish settings field). You need to set featured image for all posts/pages which should display a slider.
Is there anyway we can have the slider, images load up from one post since main goal that i wanna achieve is use this slider as a slideshow not a featured post slider for example i have the shoutbox theme and in that its possible and its way much customized than this theme help would be great to use this as a normal home page slide show
