I've created a new Sculpin extension called "Icelus". You can use it to automatically generate thumbnails of images on your Sculpin-based website or blog. I chose the oddball name because Icelus is a genus of fish otherwise known as “Scaled Sculpin”, and thumbnails are scaled images (it's imaginative, dammit!).
For those who haven't heard of it, Sculpin is a static site generator like Jekyll or Octopress (or many others). Instead of acting as a dynamic application on a web server, it takes your blog posts or website pages and outputs them as a set of simple HTML files that can be hosted on any web server.
