No valid image was loaded.

It appears to be working correctly now, and the error in the console is gone. Thank you very much. As you can see, I have a lot of articles I plan to display with your module. 

Hate to tell you this but your module broke my website again regarding no images in the article.  Had to turn it off to get access to the frontpage again. Am using the carousel theme with card.min and multiple categories. Some articles do not have any images which breaks the module/website. 

Please fix this and update the module so it doesn't break the website when no image exists. Thanks. 

I fixed it by setting a Custom Default Thumbnail in the module.
