Hello,
The image in your screenshot is the page title background, you can change it for one page only. The image on all your other pages stays the same.
– In your WordPress dashboard, go to Pages and edit the page you want to change.
– Scroll down to the Page Settings box below the content editor. If you edit with Elementor, the same options will appear in Elementor settings.
– Open the Page title tab.
– In Image for page title, upload or choose the new background image and update the page.
This image replaces the global page title background on that page only.
