image url from CDN is converted to a <p> rather than <img>

Hi, I know you haven't touched this module in a while but it does almost exactly what I need so I thought I'd ask for help anyway.

I have an image hosted on a CDN which I am displaying in my Markdown using the link.
When I run the Markdown file through the converter it is converting the link to a paragraph rather than an image. ie.

```
"tokens": [
"type": paragraph,
"text": ""
]
```

Is there a way for the converter to recognise it is an image?

Thanks
