I can't add my own permanent header image in the theme Twenty Eleven. It only offers me default options. I have done this before a couple of months ago as I started a site with a random address that I created at the time, assuming I could change it later.
However I understand I can't change the http address on the old site - so have been told to create a new one, which I've done, with the intention of exporting what I have already drafted.
But now I'm stuck as I cannot seem to recreate what I want. Can anyone help?
The blog I need help with is molehillsonthelawn.wordpress.com.
