itucakov on "Custom dimension Header Image upload in Twenty Thirteen"

Hello,

I am wanting to upload my own custom header through my child theme in twenty thirteen that has dimensions 1000x222.

I found online the option to put this into the function tab:

define( 'HEADER_IMAGE_WIDTH', apply_filters( 'basic_header_image_width', 1000 ) );
define( 'HEADER_IMAGE_HEIGHT', apply_filters( 'basic_header_image_height', 222 ) );

And this worked when I uploaded the header but for some reason the actual header image is blown up on the website and only a part of it is visible. And my image is exactly 1000x222 size. Anyone has an idea why this is happening?

Also, I noticed that the image is not getting "shrunk" if the browser size is reduced. Is there way to still retain that option?

Here's the website:

Thanks for the help
