The theme is designed for wide screen (1280px) and has a dark gray background (therefore the theme's name). There are 9 albums per page and 6 pictures par page. CSS3 is used to have a modern and light design.
This theme has been abandoned by its original developer and we provide it for archival purposes on our "unsuppported-themes-thirdpary" GitHub repository "as is". We may sometimes roughly update it but cannot promise full compatibility with current ZenphotoCMS releases. Contributions are welcome.
