You can use any image editor, such as Paint.net, the GIMP, or (if you have it) Photoshop, to create the header if you know what size to make it. As to how you change it, it may depend on theme you are using. I know in the AffiloBlueprint theme, you can change the header from the Theme Options page in the wp-admin area. Whether you can do this with other themes or not, I have not checked. Some you might be able to. But that's where I would look to see if you have that capability.
(Note that the AffiloBluepint theme is not the same theme as the blogging bootcamp theme.)
Hope this helps a little.
