Google launched a new feature for the Gmail, the Gmail pictures.

Gmail Pictures allow you to put an image to a name,

by showing user-selected pictures when you roll over a name in your inbox, Contacts, or Quick Contacts list. (link)

You can do it by choosing a picture for yourself and for the names listed on your contact, or you can leave as the picture used by other Gmail users for them.

You can choose your own photo for yourself and for your contacts, suggest a photo for a contact to use, or see what your friends have selected for themselves. (ibid)

You can even configure the Gmail Pictures to suit your preference:

Gmail pictures can be configured to show to all users who you email or who email you, or they can be limited to only those users who are able see when you’re online. You can see a full list of users who can see your online status from the All Contacts tab of your Contacts page – they’ll be listed with a colored ball next to their name. (ibid)
