Check out Microsoft’s Zoom.it, a great way to turn your high resolution images into an interactive google-maps like widget!
Here are two zoom-it’s I made with flickr photos. Use your mouse scroll wheel to zoom in and out, and you can pan around with your cursor. Or use the overlay-controls in the bottom right to zoom in and out or even go fullscreen.
Visit zoom.it if you’d like to create your own, just give it the url of a photo and let it do its thing.
