Hello,
Using the element “header” I’ve created a header for my posts. Which works really good by the way, nice work!
This header uses the featured image of that post as background image. For optimization reasons I checked what image size was used, after checking the css I saw it uses the full size image as background image, which imho isn’t optimal.
Is there an option to use the standard by WordPress created “large” images size as background image in the header element? This would help saving resources and therefore speed :).
