I've been meaning to create a new header for a while now. But, I haven't had the chance until today - thanks to a really terrible Internet connection. :-p
Unfortunately, for some reason, I can't get the image to show up. I've uploaded it, changed the header background URL, and checked in different browsers. Still, nothing.
So now, I've got an invisible new header. Ergh. I'm not sure what to do, so I'm giving up for now. Any advice welcome.
UPDATE (26 June 08): Yes! I finally got the header to show! w00t! 🙂 Ended up having to upgrade to WP2.5.1 *and* upgrading my theme to the latest version (dkret3, was using dkret2-10). Thanks for the kind words & suggestions!
