Your header is set via 'Page Header Settings' within your page. If it's not, go to the how-to for setting header via WPBakery Page Builder.
1. Om je header te veranderen moet je deze eerst verwijderen. Klik hiervoor op ‘Remove Upload’.
2. Then click 'Upload'. Choose the new image for your header from your Media Library. If it is not there yet, click on the 'Upload files' tab to add your image to your Media Library.
Please note:
Your new image should be between 1600 and 2000 px wide, and at least 475 px high. If you get your material externally, ask your designer about it.
