Directories
Define where JPT should look for source images, and where it should place generated images.
Source
Format: source: (directory)
Example: source: images/
Default: Jekyll site root.
Base directory for your source images, relative to the Jekyll site root. For example, if set to images/_fullsize:
this tag: {% picture enishte/portrait.jpg %}
will use this path: images/_fullsize/enishte/portrait.jpg.
Output
Format: output: (directory)
Example: output: resized_images/
Default: generated/
Save resized, reformatted images to this directory in your compiled site. The source directory structure is maintained. Relative to your compiled site directory, which means _site/ unless you've changed it.
