Thanks for the login…. I noticed you had an empty widgetkit widget in the Showcase position, which is why you were seeing part of the showcase on every page…there was just the container of the widget. Once I removed that, then the default header image (from the theme) showed up on the front page but then I went to remove it from going to Appearance >> Header. So now, you have a collapsed showcase area to do with as you need.
Was this what you were wanting to solve?
