Weird image next to some peoples names in my contacts

[SwindleHeart]

There's this picture that kinda looks like a webcam with a green circle in front of it, and it's next to some names of my contacts. It just recently appeared and I can't figure out what it means :/

Any help? Thanks !

That refers to your skype contacts - green denotes they are online.
