Getting my header image back…

I just installed a WordPress blog for a friend, and handing over the login keys, joked that she could feel free to play around on the site — she won’t break anything.

I came back today to find she had in fact broken something, and I’m at a loss to bring it back: using the header image and color editor within the blog, she created a gradient that now covers the header image I made for her (which is simply the new kubrickheader.jpg). I tried bringing the image back, and even checked the style.css, and header.php files, looking for a clue, but came up short.

How do you resolve this issue? Thanks in advance!
