Press on Pages and you’ll be taken to the full list of pages you created for the website.
Hover with your mouse over the page you want to add a featured image to, and click on Edit.
Go to the editing interface for that page, and in the right-hand menu, scroll down until you find the “Featured Image” option.
Click on Set featured image and upload an image of your choice.
Then, click Update to save the changes you made to the web page.
The same goes for all pages where you want to add a featured image to.
Then, you need to go to the Customizer and make some changes to the default options.
From the blue sheet icon, select the pages you’ve added featured images to.
Then, to replace the default Hero of that page with the featured image you’ve set earlier, go to Hero -> Settings (in the left-hand menu of the Customizer):
You open the panel with customization settings for the Hero of that page:
Under the second tab, named “Style”, select Image as background type, then enable the option to Use featured image if available:
You’ll see that the photo you’ve set as featured image in the WordPress Admin dashboard is now placed as Hero image for that respective page.
The same goes for every page where you’ve set featured images.
