Zoom.it is a new service from the folks at Live Labs which lets you create shortened URLs for deep zoom images. To create a deep zoom image, you can just enter in the link to any standard image anywhere on the Web. Zoom.it will covert the image to the Deep Zoom format and then return a shortened URL, perfect for tweeting.
On the Zoom.it homepage, there are a handful of examples, including a gorgeous high-res image of a galaxy snapped by Hubble, a panoramic view of an old map of Milwaukee, from the Library of Congress, an expansive panorama of Yosemite (via the Yosemite Extreme Panoramic Imaging Project) and more.
