If it’s just in the text navigation menu that you want the image to appear, you can just use the custom menu function in WordPress (Appearance -> Menus), entering your image src ( <img src=”http://full-url-to-your-image.png” /> ) in the “navigation label” box. Not very elegant and I am sure someone with more programming knowledge will be able to give you a better solution, but it works. 🙂
