title: How can I setup Jekyll for a blog with a large image directory, so as to avoid duplicating that directory in the generated site?
body: <p>I'm considering Jekyll for a site I'm putting together that will be a blog with lots of images (and other larg-ish media files). It's easy enough to to make a directory for images and then link to them as needed in the posts. But, as I understand it, when the site is generated, all the image data will be duplicated into the generated _site directory that holds the static files. Each time the site is generated the _site directory is emptied, and repopulated with the static version of the site.</p>
  
  <p>Is there any way to, for example, drop a symlink to the images directory inside the site directory, and then maybe have jekyll ignore it when the static files are generated? </p>
  
  <p>Or is there another way to go about this that makes more sense? </p>
