In late August, Bing announced the Bing Image Widget Tool and then a couple weeks later, Getty Images sued Microsoft over that tool, citing "massive infringement" of copyrighted images.
Then within a couple days, Microsoft pulled the tool, as you can see from the image above. In fact, Mark Reynolds posted a comment 2 days ago with a picture showing it was dropped.
Doesn't surprise me but Microsoft is making a statement by saying it is "temporarily" offline and not permanently offline.
Here is the page if you want to try it yourself and it does serve a server status 200, OK. Also, if you embedded anything using it, that no longer works, as you can see from my original post. (Update, the widget, if added previously, still shows)
