I have searched and can't figure out how to upload images for the header. I got all the rest figured out and love the ease of use. But after three hours or more of reading it all---I do not see how to add a new image. It's probably right there in front of me, right?

see http://forum.bytesforall.com/showthread.php?t=321
they go in /wordpress/wp-content/themes/atahualpaXXX/images/header/
where xxx is the version you are using
you will need to FTP the images to that directory
