Documents show inline with email (not just attached)

We are trying to make any document emailed be shown inline with the body of the email. Does anybody know what I would need to do?

@andrew1 they already show inline, where did you see an error?

Sorry, maybe I wasn’t clear. I meant that we wish to show Quotations, Sales Orders, Invoices in the body of emails. Not just as attachements. Currently they are not shown. Perhaps there is a configuration that we have missed.

No that is still not available out of the box.
