ImageBlur

Download extension

This extension will blur all images in img tags on the page.This plugin blurs out images in <img> tags on the current web page. If you hold "shift+alt/option" and click on an image, the image will be revealed. Features include: blur images by default, remove background images, control over blur amount, a blur image button, an "unblur" images button.

More features coming. I anticipate adding functionality to blur background images, "right-click" option to unblur or blur a specific images on a page and the ability to whitelist and blacklist specific pages/sites.
