We'll assume for a moment that your header is set via WPBakery Page Builder. If not, go to the how-to for header setting via 'Page Header Settings' within your page. Then we will help you with 3 simple steps to the desired result: customising the header with WPBakery Page Builder!
Step 1. To change your header, you first need to go to the frontend of your page. To do this, click on 'Frontend Editor' at the top of your window in 'Edit Page'. The image below will help you visualise this explanation.
Step 2. After the page has loaded, you will see a white cross at the front of your page, in the middle of the header. When you move the cursor over the header, an orange outlined rectangle appears. At the top left, you will see a blue area (row) and an orange area (column). In the blue area, click on the pencil to open the 'Row settings'. We have a preview image for this step too, to make everything a bit brighter.
Step 3. Once you've clicked on the pencil icon ("Edit Row"), a new window will open automatically. These are the settings for the row in question. Within the "Row Settings", click 'add image' to change your header image. You then choose the desired image and you're done.
Note: Your new image should be at least 1600 pixels (px) wide, and at least 475 pixels (px) high. If you have the image supplied externally, ask your designer about it to get this done.
