By Default the Page Header Background Image (set in Admin Panel -> Left Menu -> Appearance -> Customize -> ‘Header and Footer’ Section -> ‘Page Header Background Image’) is same for all page. In case you want to set a specific image as a page header background image for some page, it will require a small customization:
1.Open the page you want to set a specific page header background image for edit
2. Insert ‘Custom HTML’ block:
3. Insert the following code:
<script type="text/javascript">
jQuery( document ).ready(function() {
jQuery('section.page-title').css('background-image', 'url(https://tishonator.com/themepreview6/tishconstruct/wp-content/uploads/sites/37/2021/02/sunset-219354_1280.jpg)');
});
</script>
Replace:
https://tishonator.com/themepreview6/tishconstruct/wp-content/uploads/sites/37/2021/02/sunset-219354_1280.jpg
with URL of the image you want to set as a Page Header background image
4. Save changes
