Importing images in public dir

In Angular 2 templates, if I add an `<img>` with a relative path like this:

```
<img src="image.png">
```

I get the following error:

```
Module not found: Error: Cannot resolve 'file' or 'directory' ./image.png
```

I am forced to use absolute paths but in that case the app will only work when deployed in the root.
