Hi, I am trying to reduce the header image height on my site http://www.aristata.co. The image of the sun rising over the earth takes up too much vertical space. I've searched the forums to figure this out and am stuck. I am using the Twenty Eleven template and want to shrink the image height in half. I've looked in function.php and tried adjusting image height from auto to 160px and no luck. I've looked in style.css and tried to make same change to header size and no luck. I've used an image editor to adjust image to 1000px by 160px and WP forces cropping when I upload. I've tried the tool kameleoon to use a gui tool to resize it an no luck. I am not very basic in HTML and would really love some help.
Thank you very much for your help.
