4chan picture downloader
Usage
Install Node.js if you don't have it yet. Then from the command line:
[sudo] npm install 4chan -g
Then proceed as follows:
mkdir directory
cd directory
4chan http://boards.4chan.org/o/res/6487606
When the downloading finishes, the tool will keep monitoring the thread for new pictures, and download them as they appear, until the thread is removed. Press Ctrl+C to quit the tool. Use the option -s (--single-shot) to prevent this behavior and only donwload the existing images.
Call the program with the --help option to see more options, like filtering based on image dimensions, gif/non-gif format, and categorization of images into landscape and portrait subdirectories for easier mobile viewing.
