Image placement markup

[andreadev-it]

Hi, while looking at the spec, I couldn't find a way to place an image inside my norg file. In markdown, it is done like this:

![alt text](./link/to/image.png)

Is the syntax allowing something like that? Because when exporting to markdown, pdf or other documents it is often needed... I know that a lot of thought has been put into the specs, so this might have already be discussed, but how should we do it? Is it supported by the current spec?
