+
+## Introduction
+
+This document describes several static image gallery generators,
+their advantages and disadvantages. All of them are FOSS and
+have been tested under a Unix like operating system.
+If you have any kind of update, do not hesitate to
+[[contact me|about]]. I am using a downscaled sample directory
+(**basis**) for testing.
+
+I'm not referencing the navigation, but only "Next Image", because
+this is probably the most often used navigation part.
+
+## [cataract](http://cgg.bzatek.net/) (1.0.0)
+
+   * Next image: Click on image
