In line no 5 the $_SESSION["username"] is always set to "Ram". Thats why the problem. Please check that line.

when i removing the user session ram can't upload image in my user table.
how to set any user has login and update image

you have to set that in your login page when the user login...

'session_start()' requires on your page. But, it might be the first before output any HTML or processing PHP codes.

<?php
session_start();
?>
