I have added 6 header images in the Delicious theme, none of which I want as they are all too big and have an outline. I can't seem to delete them - any ideas how? The 'remove' button doesn't work and you can't select an individual image.

I want to load a logo there instead. How do I do this? Also, once I've added a logo, how do I ensure that when someone clicks on it, it takes them back to the homepage?

Thanks for any help....
