If you are using the Tideway or Brooklyn template for your website you have by default a slideshow integrated on the homepage. If you prefer to have a static image instead of different ones, you will have to delete the pictures in your homepage slideshow.
To do so:
- Go to your Main Menu in the top left corner and select Websites.
- Choose the website that you want to add a background image to, click Edit and select Pages.
- Enter the Home page and click Edit in the bottom right corner of the Theme widget. Delete all pictures.
- Now go into your Design section and select the tab Background.
- Then click Upload image.
