I was able to add the image. I have to edit the page via the ‘edit page’ tab that is visible when I’m actually logged into WordPress Admin and on the page (I want to edit). There’s a black bar at the top with several tabs ‘customize’ ‘new’ and ‘edit page’. Clicking ‘edit page’ in this mode allows me to select ‘add/upload file’ and import the image. The image is visible on the page using these steps.
