Hi, great theme. However, after installing it, I find that any post which doesn’t have a featured image has a random image above it in the home page… a girl with a hat, people in a street, a motorcycle, a yellow taxi, and an open road. All irrelevant. I have years worth of content so I can’t go back and assign featured images to them. How do I get rid of those standard images?
You probably have enabled the general header image and also selected to display random images from the theme’s suggested list. You can select or disable the header image from WordPress Site Identity > Header Image panel (in the customizer).
