Hello,

The Education Hub theme by default has an option to set header image at the header of all pages by default from your Admin Dashboard > Appearance > Customize > Header Image. However, currently the theme does not have an option to control the header display for the front page.

You can however use some custom CSS to target the header image in the home page and display it only in the inner pages. To do so, paste in the following custom CSS in your Admin Dashboard > Appearance > Customize > Theme Options > Advanced Options > Custom CSS :

.home header#masthead {
    background-image: none;
}

Feel free to post your requests if you have any further requirements regarding Header size in inner pages.

Hope this Helps,

Best Regards !!
