[Theme: Albar]: Can't replace demo1 and demo2 images in carousel

I’ve read the instructions but my version of the theme does not show the same options. I have images I want to put in the carousel at the top of the home page but am so ready to give up in frustration. Do I need to upgrade to Premium to get rid of two pix that are totally not relevant to our site? After many attempts, we managed to remove the images at the top completely instead of replacing them with our own. That was not what we wanted to do.
