+The meaning of the currently supported GraphicsMagick's settings is as follows:
 
  * `quality` allows to customize the compression level of thumbnails (between 0 and 100)
  * `auto-orient` change the orientation of pictures so they are upright (based on corresponding EXIF tags if present)
  * `strip` removes all profiles and text attributes from the image (good for privacy, slightly reduce file size)
  * `resize` can be used to resize the fullsize version of pictures. by default, input image size is preserved
+ * `progressive` converts classic baseline JPEG files to progressive JPEG, and interlace PNG/GIF files (improve the page loading impression, slightly reduce file size)
 
 Any GraphicsMagick setting can be customized on a per-image basis (either `cover` or `image`, see below).
