How to add a picture from an image URL

Hello, how do I insert images into the body of my website via an image URL?

Like below:

<img src="https://images..." alt="pic" />

I only found the option to add code to header, footer and lock page. When adding images to the body of a template it only allows to upload or use stock photos?

Thanks very much!

You can add a code block directly on to your page and then add the HTML for the image there.
