If you are a regular on the 4chan.org website you probably have discovered lots of great images and photos on there. 4chan is notorious for its adult section where there are almost no rules as to what can be posted, and what cannot be. But the site has more to offer than that, a large Japanese culture section for instance with anime and related boards, creative boards and interest based boards. The majority of boards on 4Chan are not adult related.
One of the issues that you may come upon on the site is that it is kinda hard to keep track of a particular thread you are interested in. You can keep the thread open in your browser and refresh it manually, or bookmark it to open it at a later time. There is however no option to download all images posted in a thread on the site, unless you happen to have the right third party tools at your disposal.
4Chan Image Downloader is such a program. The software, available for the Windows operating system, lets you download all images from a 4Chan thread and monitor that thread for new images after all of the images have been downloaded to the computer.
You need to select a board and thread number manually, or use the get from clipboard option after you have copied a 4Chan thread url to the Clipboard of your computer. The only other options that you have are the selection of the download folder on your local system, and whether you want to monitor that thread for new images or not. If you do, you can configure the monitoring interval as well.
The program displays all images as thumbnails in the interface and begins the download automatically afterwards. If you have selected to monitor the thread, you cannot use the program for anything else. There is no option to monitor multiple threads at the same time, or continue downloading from other threads while you monitor one.
If you download images regularly on 4chan, you might like to test drive the 4Chan Image Downloader application to semi-automate the downloads.
