daviddenny on "Removing the xxx img across the top of Inuit Types"

Hi

I'm trying to remove the img that runs across the very top of each page in Inuit Types (a band of what looks like xxxxxx about 6 pixels high), thought it would be quite simple but can't figure out which code to change at all, managed to find it's vertical axis here

body.logged-in {
background-position:0 28px;
}

but if I try deleting this code the image still appears.. help!

Thank you!
