Adding Personal Header to Default Theme

Hi all,

Limited in my coding knowledge here. Hope someone can help. I want to add a personal header image to the Default theme (I added a personalheader.jpg to my Images directory per comments in the code). Ideally, I would like to maintain everything I already have color-wise, etc., and just add a jpeg with a transparent background to replace the clunky- looking generic title.

code as it’s currenly written:
