It was very easy to add photos in the header working with https://www.domainename.wordpress.com but now, with my own domain, I’m note able to do this (I am Dutch, working with WP3.1 French version)
Many thanks Olly. I don’t want to add a photo in an existing header, I want for the first time add a photo in an empty header (actually only white letters, generated by the theme Weaver).
