Hello,

I'm working on a project right now and my starting point is procuring the highest resolution deep zoom image of a photo possible. I'm contacting you to request assistance - please can you advise what is the best way to do this.

Can I use any image, or do I need to start with a special digital pile such as one from Gigapan's gallery?

I'd like to have a 800 to 100 DPI zoomable image and want to create this independently if I can using zoomit (or your deep zoom controls tool)? Please can you advise what the highest DPI deep zoom is that I can achieve using 1) zoom.it, 2) your deep zoom control tools, and 3) some other method?

Thank you.

There's a brief answer to this question in the zoom.it FAQ: http://zoom.it/pages/faq/

There's no fixed limit. It depends on a number of factors, and is a function of how the image was originally enocoded. The underlying Seadragon (Deep Zoom) technology is not the limiting factor here. It's a question of how big an image can be created as a single image file. There is a finite upper limit (around 2gbytes) on the size of any one file. There are other numerical limits based on the specific image encoding format. Basically, if you can view an image on a Windows PC that means the Windows image codec can decode it. So, you should be able to convert it on Zoom.it.
