Scooby,
Thanks for your response. I guess this is how I ended up figuring it out (There is probably more than one way to do it): For each image I want to add to the slider in Landing page, I create a separate Page, on which I add a featured image. So I go to Page>Add New >feature image and I add it. And it works, well except that I do not have the right image sizes, but still experimenting overall.
Thanks for your help !
