Pinterest Allows Users to Search Using Images

Wall Street Journal: Pinterest plans to introduce technology to let users search the photo-sharing social network without using text. The new tool would allow a user who, for example, admires a light fixture pictured hanging above a dining-room table to highlight it, and then see pictures of other light fixtures in similar styles or colors. Pinterest says the technology is a step toward a new type of visual search engine that it calls “a discovery engine.”
