Google-Backed Pixazza Launches "Image Apps," Rebrands As Luminate

Pixazza, a startup backed by Google Ventures, is known for “in-image advertising,” a method of overlaying photographs with relevant ads–when a user mouses over a picture of, say, a bicycle, for example, he or she might see an offer to purchase a bike from an onlne retailer such as Amazon or Sears; if a purchase is made, Pixazza takes a cut of the sale.
