Here's a planet earth theme using a dark blue and black color scheme (and of course a photo of our beautiful planet :)). It's based on my Supernova theme and you can check out a version on my test gallery at http://www.bullseyephotos.com/gallery/index.php?theme=terra (http://www.bullseyephotos.com/gallery/index.php?theme=terra). I created these themes as an exercise in understanding the style.css and theme.php where I've documented the css styles and what they control and will post as a help doc soon.
Cheers,
Billy
Thanks for the contribution - the theme is very nice indeed and a great addition to the project. I have added it to the demo (http://coppermine-gallery.net/demo/cpg14x/index.php?theme=terra) and download (http://prdownloads.sourceforge.net/coppermine/cpg1.4.x_theme_terra.zip?download) section
