How to embed an image
1. Images have to be hosted by a hosting service (like https://imgur.com/upload) or any other hosting service.
2. After uploading, right-click on the image and click "copy image address".
3. In the Vocus.io message editor, click on the "<>" to insert HTML:
and type:
<img src="image_url" width="400" />
4. Replace "image_url" with the link you copied. Then click on "<>" again.
