I wanted a new look at my site and chose the Nishita theme. When I tested it to see what it looked like, it came up with the header I was using previously using Twenty Ten, a person walking down a road with threes on either side. (This header always appears with Twenty Ten when looking through the Theme site.) It worked very well with Nishita. Then when I activated the new theme the header disappeared. How can I find this again?
I went back to Twenty Ten and applied it to my site and it came up just as I had it in the past but the header was different. Is there a way I can find this header again and apply it to the Nishita theme?
The blog I need help with is mertonocso.wordpress.com.
