How can I add a hi-resolution logo (also called retina) to the theme?
If you have a monitor with double the pixel resolution classic images looks blurry.
it is easy to see if you got a smartphone (iPhone in my case) and also on my brand new MacBook with retina display that the logo is blurry.
Any code that will pick up the hi-res version “email@example.com”. It is actually a double sized image of the classic image to show nicely in the header?
