Bitbucket static pages can't serve static assets from nested directories

[weiss10700]

Bitbucket.io doesn't serve images.

I have this directory structure for images
```
/public/img/file.png
```

And I have this in my `index.html` and Bitbucket.io cannot find and image file.
```
<img src="public/img/file.png" >
```

How does it work? They have no documentation on that. Can Bitbucket.io serve static assets from nested directories?
