In the 'de' Wikipedia you can reference a piction from commons as
follows:
[[Bild:Hagen Osthaus Museum Traditional Main Entrance keichwa.jpg|thumb|Osthaus Museum]]
If you click on the thumb you will be taken to:
http://de.wikipedia.org/wiki/Bild:Hagen_Osthaus_Museum_Traditional_Main_Ent…
Where you read:
This file is a shared upload and may be used by other projects.
This is not enough. Please include the description from "commons" and
provide a back-link to
http://commons.wikimedia.org/wiki/Image:Hagen_Osthaus_Museum_Traditional_Ma…
;
[[:commons:Image:Hagen Osthaus Museum Traditional Main Entrance keichwa.jpg]]
seems to do the trick.
If you do not provide some such info, you don't have the right to copy
the image from "commons". I release it under the conditions of the
"Attribution ShareAlike 1.0 License".
IIRC, you talked about the weakness of the current system soem months
ago - it is hard to believe that this rather serious issue is still not
fixed.
