When a non-Wikimedia site places an image from a Wikimedia site directly on one of their pages, users likely won't know that it comes from Wikipedia or the Commons or who originally created the image. They might think it was created by the linking site's own staff or comes from a commercial stock-image collection. It also means bandwidth gets used up without bringing in any name recognition or visibility for the Edit This Page links. Many wikis would probably at least like to add the description-page URL to the file's metadata. I think wiki server roots should be able to choose what to do in this situation:
* Do nothing.
* Add a metadata watermark where possible, otherwise do nothing.
* Add a metadata watermark where possible, otherwise add a visible/audible watermark.
* Add a visible/audible watermark.
* Ban hotlinking. A file cannot be downloaded with a referrer other than the hosting site (and possibly a white list of other sites).
Not currently planning to do this.
WONTFIX, we allow hotlinking.
