A western Pennsylvania couple has sued Google Inc., saying pictures of their home on its Web site violate their privacy and devalued their property. Images of the home Aaron and Christine Boring bought in the Pittsburgh suburb of Franklin Park in October 2006 appeared on Google's "Street View" feature, which allows users to find street-level photos by clicking on a map. "A major component of their purchase decision was a desire for privacy," according to their complaint, filed Wednesday in state court, which also says the couple suffered mental distress. The images must have been taken from the couple's long driveway, which is labeled "Private Road," and that violated their privacy, according to the complaint. To gather photos for Street View, Mountain View, Calif.-based Google sends vehicles with mounted digital cameras up and down the streets of major metropolitan areas taking pictures. Many other companies take real estate photos the same way.
