How to embed an Image URL in an article?

I am trying to embed an image URL into an article so we can quickly replace images by just updating the image url in our image repository. How do I do this in Intercom? 

I tried putting the code 

<img src=”https://examply.io/image.jpeg”/> into the Insert Code block but this populates no images, as if the code does not work but the code is correct. I followed this article on Intercoms website that states you CAN insert this type of code into a help center article. Any advice is appreciated!
