Today when i logged in to my gmail account, i saw a New features! link on top right corner. And, on the new features page, they say that Gmail is soon coming up with Gmail Pictures.

We would be able to associate a picture with an email address in our Contacts or may be we can associate our picture with our gmail account.





Even, there is a screenshot which shows, you can suggest a picture to another user.
Also, Gmail Chat will have a ping sound when a message is recieved. makes it more noticeable...
