Featured Image : Header Image Replacement
This demonstrates the Featured Image : Header Image Replacement on Single Page View, not shown on blog view.
This post example uses the Per Post options to set the Featured Image layout.
This option is also available with Per Page options.
The featured image is set to be the replacement for the header image.
How the image is displayed (standard header, bg, etc.) depends on the global header image setting.
