Problem

Is there a way to select images that are used (il_to NOT NULL, linked to by any other page)) or unsed?
I want to return a simple list of unused images, but also in combination, e.g. unused files, uploaded by a specifed user.
This should actually return a simple list of 5 unused files (if I understand the parameter correctly), but it doesn't.

{{#dpl:
|namespace=Image
|notlinksfrom=%
|count=5
}}
