Hello,

It is not possible to add an image to page background using theme options.You have to set it up via css. Please add this code into your custom cs box:

#content {
    background-repeat:no-repeat;
    background-size:cover;
    background-attachment:fixed;
    background-position:center top;
    background-image:url('https://codeless.co/tower/default/wp-content/uploads/2015/05/black-white-compressed.jpg');
}

Edit image url, to the one you will use.

Best regards!

Hello,

To target just one page, go to that page’s options > custom css(screenshot) and add the code above above (screenshot). It will affect only that page.

Thank you very much for the consideration and your rating.
The follow-ups is currently not available. We are working on it. Thank you for the patience.

Best regards!
