One Line Gallery
One File Gallery is an image gallery consisting of just one file. Upload the file in your image directory and voilá - you're ready to roll. One File Gallery can be used with hierarchically stored images.
More information soon. Until then, see the example at http://www.edgesoft.de/projects/free/onefilegallery/example/. Or look at the information at https://sourceforge.net/projects/onefilegallery/.
