Microsoft Live Labs launched “zoom.it” for viewing and sharing high-resolution imagery. You can upload any website link, image, webpage, pdf, etc and get back a fully embeddable, short url’d viewer with deep zoom functionality.
For e.g, here’s our site diTii, also, embedded below:
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 Silverlight to provide the richest, most fluid zooming experience possible.
Oh and they added a boomarklet so you can apply the effect to anything you’re browsing.
