Click An Image To Go To A Page

How do I add images to my home page to click and be taken to other pages on my site? I want thumbnails on my home page to click to other pages in my site. An example of what I’m trying to achieve can be seen here:

I don’t have a site set up yet but on this site, when you click on an image you are taken to another page in the site. How do I do this?

Thank you!
