Making the header a hyperlink

Hello,

I am very new to wordpress and added a blog to my website last night. https://www.NotYourTypicalBigfootMovie.com.

I was able to go in and replace the header with one of my own, but I’d like to make the header link back to the main page of the website. I’m having a tough time figuring out where that image is actually located – “head1.jpg.” – and how to make it link back.

Can anyone help?

Thanks a lot.
