Can you please help to explain how I can link the home page slider to my web pages rather than my latest posts? I really like the slider option, but would rather use it to show a nice image and a brief introduction to my menu pages rather than my latest posts. Thank you very much in advance for your help.

You can do that with Penci Slide plugin, however it has only two styles.

You can add custom images and URLs to the slider, not necessarily a new post.
