Display high resolution images quickly and efficiently
On-demand delivery of image sections provides immediate viewing without lengthy downloads.
  Downloading and displaying a large, high resolution image on the web is an inefficient process. When the image is requested, the server streams the entire file down to the browser. During this slow and bandwidth intensive process, the image will begin to render. Depending on the type of image being transferred, the rendering is manifested by either a top-down filling of the physical window (GIF, TIFF, JPEG), or a gradual sharpening of a rough, pixelated version (interlaced GIF, progressive JPEG). In either case, the end-user must wait several seconds before seeing a usable image. This is a time-consuming process which can quickly frustrate end-users.
Eliminate lengthy downloads for high-resolution images.
A more efficient and usable approach is to deliver only the visible portion of an image to the client. By default, Zoom displays a reduced version of the source image. When a user zooms into an image detail, the server delivers only the portion that will be visible at that location.

As the user pans across the image, more details are streamed on-demand without reloading the page or interrupting the user experience.
