Hi,
a moment ago I found that the article
http://en.wikipedia.org/wiki/Panthera
contains a big OS X (tiger) image. First I thought that this is a joke, but then I discovered that it seems just to be a mistake, but one I do not know how to avoid efficiently.
The Panthera article contains a link to Image:Tiger.jpg which is loaded from commons (http://commons.wikimedia.org/wiki/Image:Tiger.jpg). Yesterday user WikiED uploaded an image Tiger.jpg with the Mac OS X to _en.wikipedia.org_. Loading the article now means that Image:Tiger.jpg now refers to the en: version of that image and by that the article now shows a different image (of course without showing anything on my watchlist).
As user WikiED probably does not know about commons he probably did not know that his upload caused problems in several articles. Is there anything one can do about avoiding such problems, e.g. is it possible to force a load from commons? Something like commons:Image:Tiger.jpg unfortunately does not seem to work. Also in the upload form it would be helpful to get a warning about a potential naming conflict.
best regards, Marco
