Jekyll Thumbnail
Adds a liquid tag that can generate thumbnails, with watermarks, at any size you dictate.
Usage
Require the ruby gem in your Gemfile...
gem 'jekyll-thumbnail'
Then, use it in your Liquid templates as follows:
{{ "{% thumbnail path/to/image.jpg 50x50 " }}%}
This will pass the image through the thumbnailer, and generate a thumbs/ directory where the image is located.
Thumbs directory
Images that already exist are not re-generated, so you can save yourself some work by caching these files.
Unit Tests
