Hotmail/Outlook question


New Email
I have the hotmail email with

I noticed in the lower left corner 14 pictures of people and some babies with some I know from skype and others I do not know.

My question how do i get rid of these pictures they seem to be people from skype but non of these people are in my skype contacts. I have been trying to find out where these pictures are coming from and what they are connected to.

Somehow there is a link between skype and hotmail and would like to get rid of the pictures is there a way?
