This JSON file is automatically generated when you use the image conversion scripts that we distribute with Diva.

IIP creates the image tiles and other image representations "on the fly". Instructions for building and installing IIP are available on the [project's website](http://iipimage.sourceforge.net/documentation/server/). If you want to support JPEG 2000 you will either need to download a pre-compiled version (available on the [Old Maps Online site](http://help.oldmapsonline.org/jpeg2000/installation)) or [purchase the Kakadu libraries](http://www.kakadusoftware.com) and build it yourself. Diva relies on a JavaScript Object Notation (JSON) file that contains data about your document. This JSON file is automatically generated when you use the image conversion scripts that we distribute with Diva. These files can be served using a regular web server. _(If you used previous versions of Diva, we had a dedicated `divaserve` script to do this. This dependency has been removed in version 3.0)_. -Download the [latest release](https://github.com/DDMAL/diva.js/releases) of Diva.
