I too am having issues with the header image. I would like to remove the screen effect and no matter what size I make the header image, it always displays too large. This is causing the header image to crop in the browser. I have tried 1600 x 400 and 800×200. Both display too large.

How does one remove the screen effect over the header image?
How does one get the header image to fit the top of the web page correctly and scale with the browser size?
