I have a header that I made 500 px wide. I noticed that the header.gif does not go all the way across to the desired margins. When I go to a 1024 x768 resolution it looks even smaller. Are there any suggestions I can do to make the image fill my entire header space? I am inserting the header in CSS. with a no-repeat.
