Remove Rhythm logo

I have the Rhythm theme. I am able to change the header and footer Icon on all of the classic pages, however I can’t figure out how to change them on the “Photography” pages. I continue to have this problem even after installing your plug in. Please help. By the way, I am not computer literate. This WordPress has been an 4 month experience in hair loss for me. So please, break it down Barney style for me.
