Profile Image Request

When we add a user to the contact list, we must now add an image of our gallery.
It would be interesting if the image could be requested from the user through its UID

How does it work?

1. Add user using UID, hereinafter we will call **YOUR-UID **.
2. ** Profile picture is requested from ** YOUR-UID **, the application includes ** MY-UID **
   2.1. ** YOUR-UID ** verifies that ** MY-UID ** is a valid user (it is in your contact list)
   2.1.1 If in contacts; Send image
   2.1.2 If not: refuse
