Index of / error

I am new to this web design thing and am not quite sure what I am doing wrong. I have put up my website
When I visit it though all I get is the websites index. I can click on the various photos and links and they all open up and look the way I would like but I want them to do that at the start of the page.
Please help!

You need to rename that “link to org.html” so it’s index.html instead.
