Zoom.it converts your image to the Deep Zoom format, which lets you smoothly and efficiently explore the whole image, no matter how large.
Zoom.it runs on Windows Azure and takes advantage of Microsoft Silverlight to provide the richest, most fluid zooming experience possible.
Why Zoom.it? “We think every image on the web should be a beautiful, high-resolution one. Zoom.it gets us one step closer to that vision, and Deep Zoom keeps the experience fast and buttery smooth.”
Zoom.it has been created by Microsoft Live Labs, the same folks who brought you Photosynth and Pivot.
