When inserting an image into a post, WordPress uses absolute URLs to the files. This plugin overrides that functionality and forces it to use relative URLs.
For example:
WordPress Default:
http://www.example.com//www/wwwroot/img.feibisi.com/2013/04/example.jpg
Plugin Override:
//www/wwwroot/img.feibisi.com/2013/04/example.jpg
This is particularly useful if you plan on switching domains ever as well as reducing HTTP requests.
