Std theme: valign of text in top?

Hi. I’m using the standard theme coming with WP.
However, I’ve changed the header image to one of my own – but now the text on the header image is in a part of my new image where it cannot be seen very easily.

How do I manipulate this text around in the header section? I’v tried vertical-align: top on both #header and #headerimg – but without any luck – the text simply does not move.

Any clues as where to edit?
