There is no easy way to change the header in the WordPress themes provided with the Affiliate Blog Bootcamp. At least not in the way that changing the header is easy to do in the AffiloTheme. But it can be done if you know how to edit images and are confident with downloading and uploading files.
You will have to download the file named header.jpg from the theme files on your hosting server. It would be in public_html/wp-content/themes/<name of the theme>/images/
After downloading, you can edit header.jpg with any graphics software, like paint.net, but be careful not to change the dimensions of the image.
After editing, upload the header.jpg file to the same location you downloaded it from.
Please remember to save a copy of the unedited header.jpg file somewhere on your computer, so that you do not have to re-upload all the theme files in case you want to go back to using the original image on your blog for any reason, like if you don't like the way the edited image looks
Alternatively, you can name a totally different image file header.jpg and upload it instead. Just make sure that the new header.jpg file has the same dimensions as the one that you downloaded from the server.
