Picture on main page

I have been using Zencart for so many years. What a wonderful shopping cart! Now I am setting up one for my wife, and going through setting hers up is taking forever. I don't know how to search for the answer to this, what keywords to search for, no search results are accurate. So I hope you don't get annoyed if its posted before.

My website, the one that has been up since 2006!! is at:
https://www.BryanKollar.com

When you go to that page, you see a picture of my store. That store picture is named store.jpg.

I am trying to add a picture in that location on my wife's page:
https://www.NewBeginningOils.com/index.php

What file should I edit so I can upload her picture and put one there like I have on mine?

Thanks!!!!

Found it.
