Blurs images on 4chan. Catalog view - double click image to unblur and open the thread. Thread view - click image to unblur, click again to reapply blur.
4chan Image Blur Toggle is a simple user script designed to obscure all images on 4chan by applying a blur effect in both thread and catalog views. In catalog view, clicking a blurred image will unblur it, while clicking again opens the corresponding thread. In thread view, clicking on a blurred image reveals it, and clicking again reapplies the blur.
