On my site I’ve set the header to image and this is very thin and not the dimension of the image. how do i make the height of the image larger as cropping isn’t changing anything. if its possible can i set this so the width is the same as the screen size and the height is the same proportion as it is by default.
You can set the header image’s height from: Customize > Header area > Header media > Header height.
Please try to set it value to
500 or bigger.
Also, please make sure you upload the header image with big dimension, 1920 × 1080 pixels.
