WordPress Theme Preview is a site, born from a frustration at the inability to preview the administration pages on premium WordPress content. There's many sites that allow you to preview how the sites look, but it's really hard to see how they will work with your content, and how flexible are the theme options? Well now you can find out.
The idea came from running my own themes site, Pro Theme Design. I created a preview area, essentially a WordPress multisite install with a few custom plugins, and realized that actually everyone seems to like it. It certainly gets used a lot, so perhaps people would like to test themes by other developers as well.
WordPress Theme Preview is built by me, Ben Gillbanks. Online I am best know for my website - Binary Moon, my premium themes website - Pro Theme Design, and for maintaining the PHP Image Resize script - TimThumb.
