google maps widget could not load image

I have put the widget in a sidebar. Everything works fine except there is no map image. The link to load the Lightbox map works fine and the map comes up in the lightbox. There is still no map image in the sidebar widget.

I have obtained and added the Google API key in settings. Am somewhat perplexed as to why it is not working

What I have done to troubleshoot the problem:
Used Inspect Element in Firefox. It told me “Image could not Load”

Any help would be appreciated
