This module is simple, you install it and you just need to go to the chapter of your choice. A "Download crawljob" button will appear near the previous/next buttons at the top of the page.

This .crawljob file allows you to download the chapter with each images having the right filename automatically. I personnally use JDownloader2 to download the actual chapter.

Please see this url to know how to use crawljob files.
