The homepage image is the picture that appears on your home or landing page when a visitor views your website. Some themes have multiple images in a grid or slideshow, while others have just one. You can change your site's homepage image at any time.
Where does this image come from?
The homepage image that automatically shows up on your page is your cover photo on Facebook, or in the case of sliders, your cover photo album.
