Custom Header Image

Hello everyone. I’m trying to install a custom logo into my header.
I’ve inserted it into the images folder (logo.jpg) but for some reason it won’t upload onto the header.

Original code:
#headerimage {height: 280px; background: url(‘images/header.jpg’) top right no-repeat; list-style: none;}

My attempt:
#headerimage {height: 240px; background: url(‘images/logo.jpg’) top left no-repeat; list-style: none;}

The default image will disappear but my logo is nowhere to be found.
What am I missing here?

Also I’d like to move the heading only about 2-4 spaces to the right. How can I accomplish this? When I align ‘right’ it moves the text too far.

Any help would be greatly appreciated. Thanks.

Fernando
