wpfolio 1.72 header

Hello,

I´m using wpfolio 1.72. It is perfect, but I don´t know html, so I can´t make changes. The only change I would like to have is, my logo should appear in the header. I havn´t found help until now. Perhaps there is somebody who could give me an advice how I can mange it. I already have activated the child theme and have a logo.jpg in the image-folder.

I´m grateful for any help.
Thanks
