RESOLVED! (kind of)
Kaspersky has an "anti-banner" feature. After digging thru my firewall and vpn settings it was Kaspersky. Turning off anti-banner allows images to be downloaded. Someone with more knowledge than I have would be needed to explain why downloading metadata would cause Kaspersky to be triggered to block it. I use other programs, for other media formats, to get metadata. Kaspersky never got involved.
Anyway, now back to checking this program out! It appears that I might need to be patient with getting the initial library done.
