Cool banner, Dan.... though you might make adjustments to its width when you add this to your blog site as most screen sizes are at least 800 pixels or 1024 pixels wide - some significantly wider. It does depend if you want your banner graphic to stretch across the page width however, you make not want that.

Happy to show you how to customise your blog site and add this banner graphic.

I'm impressed that you managed to insert a graphic and hyperlink into your comment. Did you use HTML?
