home page slider – static image

Hi everyone, i have some trouble with the home page slider, i’m using the klasik frameworks theme and i need in home page a static image. i set a static page for the home page and i set in a post a feature image and check the box “feature on home page slider” to have a single static image as slider in the home page. but the slider is a carousel, how can i set the slider as static image? this is the link for the test site https://meanless.altervista.org/

i just don’t need any transiction or paging arrows or stuff like this, only a single static image as slider in the home page

hope someone can help me, the klasik theme support does not answer to my questions
