I edited the image (to make it lighter or "whiter") and replaced the old header image with the new one.

On most websites, with Firefox you can right-click on images and see an option to "View Background Image". Since that site has right-clicking disabled, I used Firebug (or Chromebug if you use Chrome) to look at the site's HTML and CSS. This let me find the direct URL to that background image.
