Zoom.it is a neat application for displaying large images in blogs, wikis, and websites. Zoom.it creates a display of your images in a format that allows you to zoom in, zoom out, and scroll around a large image. To use Zoom.it your image does need to be hosted online somewhere (Flickr and Picasa work fine). Then to create your zoomable image just copy the url of your hosted image and paste it into Zoom.it. You can then share your image by giving people the direct link to it or embedding the image into your blog or website.
