I see the possible benefits of such a magic word, but HTML comments ( <~-- --> ) or removing the image altogether are equally workable...

I can't really see the benefit here...the reason we show missing images as broken links is to encourage them to be fixed (either by uploading said image or removing said link).

Suppressing this ability would make it less likely for people to find and fix these things. Suggest WONTFIX.

This magic word will help administrators in patrolling unlicensed images. Administrators delete a lot of unlicensed images every day and finding the correct broken image in articles source text is a time consuming job. Sory for bad english.

So instead, you'd suggest they add a magic word and hide the images? Seems like it just adds extra work in the long run for a short-term visibility fix. IMO: having broken images displayed as such is more helpful than hiding them for stylistic reasons, it promotes fixing, as I said above.

Thats part of the admin's responibility when deleting images (There are also many scripts that automate the task from my understanding).
And it's not that hard to find the file either, just copy it's name and then go to the article in edit mode and press [CTRL]+[F] in most of the major browsers and find it.
