I figured out how to do this.

When you upload image.jpg for the TwentyTen header, WordPress creates a cropped version of the header image, calls it cropped-image.jpg and saves it in wp-content/uploads.

All I had to do was find the cropped-image.jpg file in cPanel and replace it with the the 1880 x 396 version. Now it works perfectly. WordPress calls up cropped-image.jpg, scales it down to 940 x 198, and displays it on the header, but because it’s @2x the size, it looks perfect on Retina displays.

Thank you, the code worked perfectly! ??

And is there a specific place I need to add it to the functions.php file or can I just throw it in at the end?

Is it difficult to create a child theme? I went on the link you provided, but it seems so complicated for a newbie like me.

Can I just edit the existing functions.php file and it would work so long as I don’t update my theme?
