A very simple image gallery. Just upload files and application to a web-directory and have the application resize the images and display them on a single page. Nothing more, nothing less.
Just add your photos to the photos directory, when you open the page for the first time it will take a while to load (all the thumbnails are created the first time) There is a simple config file (ssg.conf) to change certain parameters.
If you like to see how the gallery looks like, check out the wiki, I added two screenshots: /~https://github.com/stravag/simple-single-gallery/wiki
