4chan Image Downloader

4chan Image Downloader is a simple, easy to use application specially designed to help you download images from 4chan threads.
This tool was developed so that it monitors the thread for new images until it 404's, thus ensuring that you will get the image that interests you.

So, all that's left to do is select the board to monitor, the thread number, the download folder of course, and just sit back and let 4chan Image Downloader take care of the rest.
