I finally got round to experimenting with a photo banner for the site. This is a standard feature in most themes and cropped a picture and uploaded it via the Appearance -> Header dialogue panel. It looks like this,….not what I wanted; it takes too much vertical space. I was hoping for the header to be above the tabs in the black area. Perhaps I can experiment with it, or maybe take a vertical slice through the picture and experiment with three column themes, with the photo banner on the left, like the Vin Rouge theme at CSS Zengarden, or maybe I should look at using backgrounds rather than headers.
I removed it.
