Several photos suddenly appear besides some of my contacts

[Dansole]

I can't say it was the recent upgrade but all of a "sudden" there are photos besides several of my contacts. How can that occur? I saw a post about facebook, but I'm not a member of facebook. I do sync the contacts to my google account.
Any ideas?

Thanks

Those contacts probably have Google+ profiles that include a picture. Whenever I add a contact who has created a Google+ profile, that contact will automatically grab the person's profile pic.

Thanks, you are correct. Was able to match up photos except for one .
