Yes, definitely the way image search is supposed to be, available only to users of Microsoft products, and only those who use the extremely secure IE6 or IE7.
I guess Microsoft does, since the URL is msresearch.us. Am I the only one that finds it strange that Microsoft still thinks they can succeed by trying to lock out the competition through tricks like this? The idea of a computer on every desk running Microsoft software is a perfectly fine goal, but that doesn't mean that they should run only Microsoft software. I can't believe that they still refuse to acknowledge that anyone else is capable of writing software that someone would want to use instead of their own, such as Firefox.
