That's fine - I've only changed the root, I'm happy to not think about the rest for now.
eta: just seen you've added to your post. I've even more confused now - this (below) is what I see as my root page. I haven't named any images - there's not even any images IN the portraits and pets galleries - they're in folders in the inbox. (I still see that line when I'm logged out as well). And there's most definitely a slideshow in there.
hang on - let me move the photo...
