Wolfram Blog: The Incredible Convenience of Mathematica Image Processing.
Mathematica 7 adds a suite of image processing functions from trivial to highly sophisticated. To apply them to images, you don’t need to use any form of import command or file name references. Just type the command you want to use, then drag and drop the image from your desktop or browser right into the input line.
Whoa. They are doing crazy stuff in Mathematica now.
