NIH Image

NIH Image is a public domain image processing and analysis program for the Macintosh. It was developed at the Research Services Branch (RSB) of the National Institute of Mental Health (NIMH), part of the National Institutes of Health (NIH).

A PDS format plug-in “Voyager_PDS12.cpt.hqx” is available which enables viewers to read PDS formatted Voyager, Viking, and Magellan images. PDS Plug-in: Voyager_PDS12.cpt.hqx

You can download the latest version of NIH Image (1.63) from the NIH Image web site,, or by clicking on the following links. It can also be downloaded from mirror sites in Sweden and the UK. See the release notes for a list of the new features and bug fixes.
