public html directory

Advert test
I think I know the answer to this but just to be on the safe side I want to confirm it here.

When you store images outside the public_html directory, then you can NOT display these images like this:

<img src="../../../not_public_html/images/photo.jpg">

or like this

<img src="/home/mydomain/not_public_html/images/photo.jpg">

Am I right?
