You either hate or love 4chan, the popular anonymous image posting bulletin board. It is basically an image posting forum with the ability to post replies that also include images. The website itself is divided into subforums that range from Japanese culture to creative forums and also the notorious random forum which has received some criticism in the past because of the pictures that have been posted there.
The 4chan.org Dumper is a simple command line utility that can be used to download an entire forum or part of a forum with one command. A forum at 4chan usually consists of 15 (or so) pages with posts by users.
The basic command to download images from a page at 4chan is [dump4chan.exe [url]]. There are a handful of optional parameters that can be added including the ability to select a specific output folder, to dump the whole board, the replies and to hide the command line on the screen.
The command 4chan.exe http://zip.4chan.org/v/imgboard.html videogames -all would for example download all images from the video games forum at 4chan and save them in the videogames subfolder. Duplicate images will be skipped automatically. Users who want to download pictures regularly might want to think about creating a batch script for the process to be able to do so more comfortable. 4Chan Dumper is a free software that requires the Microsoft .net Framework.
