United Online, the parent company of e-mail and Internet service   providers   Net Zero and Juno, and of social networking site Classmates.com, bought   digital photo services company PhotoSite Friday
for $10 million cash.   Currently, about 3.1 million users access the Internet through Net   Zero,   which offers both free and paid subscriptions. United Online plans to   integrate PhotoSite into
other properties, and also intends to keep it   as a   stand-alone service, said a company spokesman.
