I tried Firefox first, then Chrome with several zoom levels including default with no success. I even changed the resolution on my Win 10 laptop a few times. I was so desperate I launched the new Edge browser. It seemed to be more forgiving and displayed the webpage without generating the error no matter what my zoom level but no-how could I get it to display the provided Google image in jumbotron (Nor my own image for that matter). Strangely though, Neighborhood Guides thumbnails showed up properly). This was the exact same code (I know because I was copying working code to notepad for each step, then ensured I'd logged out of FF and Chrome before logging into Edge. So, web gurus, any ideas?
