If I wanted to add zoom to all of the images on a web site (thousands), would there be a limit to how many can be uploaded? How long would it take to process a large number of images?

zoom.it has no individual accounts, so there is no limit on the number of photos any single person can upload. That said, there are two important things to consider:

- zoom.it is not an image repository; it's a cache for high performance viewing of large images. Your images still need to exist at their original URL. If zoom.it has space limitations, it may delete your image from the cache. The next time it is requested to view, it will re-create it again. (The viewer will see the "fetching", "converting" messages, etc.) While this rarely happens, it is definitely a possibility.
- zoom.it was created as an experiment by the now-closed Live Labs team. While there are a handful of us former team members that maintain it, I can't make any guarantees about the site's future. This is something to consider before using it for a large scale production operation.

As an alternative, you can create your own zoomable images using Seadragon Ajax, an open source control that is part of the ASP.Net Ajax Control Toolkit (http://www.asp.net/ajaxlibrary/AjaxCo...). There is also Open Seadragon (https://github.com/openseadragon), a modified version that works without dependencies on ASP.Net.

One of the great capabilities of zoom.it is the ability to seamlessly use either Silverlight Deep Zoom or Seadragon Ajax depending on the client's capabilities. But with the continued performance improvements in modern implementations of JavaScript and the declining support for Silverlight, this has become much less of an issue than when zoom.it was first created. Seadragon Ajax and Open Seadragon both provide nice solutions for reproducing the viewing capabilities of zoom.it on your own website.

Is there phone support available for Seadragon Ajax through Microsoft support?

Argon, I just wanted to chime in to say you could download Deep Zoom Composer which includes DeepZoomTools.dll which you can batch process images with from the command line if you prefer that to Deep Zoom Composer's graphical user interface.

When you output a single image or sparse image (multiple original images arranged in a static layout like the bicycle example on the zoom.it homepage) rather than a deep zoom collection (which requires Silverlight to view) Deep Zoom Composer will give you the same Seadragon Ajax/Silverlight combo viewer that is used on zoom.it, but with the original Seadragon logo in the lower left corner of the viewer.

Using the original Photosynth application is another simple way to convert your images to deep zoom images and Photosynth.net offers several free gigabytes of image hosting per account. The deep zoom image URLs can be found in Photosynth's log file located in the %temp%\Photosynther folder on your hard drive after your upload has completed.

You're not likely to get phone support for Seadragon/Deep Zoom since the teams working on it have disbanded but the tech still works and you can find a bunch of questions and answers about Seadragon Ajax here on Get Satisfaction and pick up more about Deep Zoom Composer from their old blog.
