I’m assuming you are using the free included Default template, correct? If that is the case, navigate to the Connections : Settings admin page and click the Customize button for the Default template.
The page will refresh displaying the Customizer on the left and a preview on the right.
Click the back arrow in the upper left of the Customizer and then click the Image panel.
Choose the desire image to display.
Now, carefully read the instructions displayed above the directory in the preview.
Click and entry name in the directory list in the preview and make the Image change again.
Publish the changes and exit the Customizer.
Hope this helps. Let me know.
