Hello Alexandro,
There is no option to add background image(Featured image) for inner page title in our theme. If you share your WordPress credentials with us on our support email id: “[email protected]” then we can add it for you. But we need to custom work on that so you need to pay a small amount for this work only $6, link is made for $3, pay the amount by adding 2 quantities. You may pay this amount using the link below.

Theme Changes

Thank you.
