The acquisition comes on the heels of , another wildly popular photo app.

Google obviously didn't want to be left out of the photo sharing craze so now the two social networks having dueling photo apps, analysts said.

Zeus Kerravala, an analyst with ZK Research, said an acquisition like Nik Software can only be a boost as Google gains ground in the social networking business.

"This is a move to combat what Facebook did," Kerravala said. "Obviously, we live in a visually oriented society so its almost a must-have. Making it easier to add photos is a capability that is table stakes today. It fixes a big hole in Google+."

Despite today's announcement, Google+ skeptics remain.
