Dreamwidth style system discussion

You're most welcome!

Pasting the temporary fix via custom CSS (http://www.dreamwidth.org/customize/options?group=customcss) if you or someone else needs it:

#header {
background: url(http://yourimage) no-repeat top center;
padding-top: 100px;
}

'padding-top' being the height of your image.

And to make sure the image is centered in left or right sidebar mode:

.two-columns-right #header,
.two-columns-left #header {
margin-right: 5%;
margin-left: 5%;
width: 89%;
}
