Hi @nutch-dev, I want to put out this [0] tutorial over Nutch wiki.
1. Do you see anything wrong in it or any improvements ? 2. Where do I upload the images ? Wiki will allow me to just specify the url.

This is different from the one over the wiki page and tailored for Nutch 2.x. Please try it out, let us know if you still have issues with that. Based on your comments, I would add the same over nutch wiki.
