I only changed the pre-defined variables. Perhaps these don’t exist in different versions? My specs are:
Using WordPress 3.9.1
Theme: Highwind 1.2.4
Steps:
From the WP Dashboard, go to Appearance -> Editor and edit the highwind-functions.php file. For me, I changed lines 16 and 17 to be:
‘width’=> 2000,
‘height’=> 400,
Save the file. I then followed the routine steps to uploaded a new header image (which automatically crops using the new dimensions), and got a better look for my header.
Hope this helps.
Cheers!

I didn’t like the default ratio, so I modified the highwind-functions.php page to use 2000 x 400.
Uploading new images will autocrop to this scale instead, and (I think) looks a lot nicer.
Your mileage may vary.
