[scribus] How to extract embedded images?

[Henk van Andel]

Our association magazine is DTP'ed by several voluntees, using Scribus 
(of course).
In order not to loose the images in all kind of 'obscrure' 
(subdirectories, we embed the images (have in on clipboard, paste from 
clipboard). This works fine.

However, sometimes one wants to extract the images from Scribus.
There is a procedure, but I cannot find it.

Can anyone help me to find this procedure?
Is it in the Manual (I have it).
