Header Alignment Problems


I'm having a hard time getting a custom image to display properly...

I've uploaded a 950x80 image (tried png, gif, and jpg) in the custom header section, but it doesn't display correctly: it repeats and the first part of my logo shows up again on the right side.

So I tried doing uploaded a large image in theme options and that also doesn't display properly, and has undesirable padding around it.

Is there a way to change the header.php to simply show my uploaded header image? and not have extra padding at the bottom between that and the categories?
