Adding a featured image to a basic page include
You can add featured image to basic page include by adding a slide in the include page's 'Featured content sliders' section found in the page 'Settings'.
As with a header image, if you don't want the featured image to link to another page you can add the same slug as the include page in the 'Page to feature*' field.
If you add more than one slide then they will appear as a carousel wherever the page is included.
You can see an example of a basic page include with an image below:
