Link not displaying from db

Question

I have a login script, and a table with fields, the one required here is 'avatar'( varchar(255) & defaul entry is an image link)

Code for viewing the profile:

<div align="center"><img src="<?php echo $_GET['avatar']; ?>" width="250" height="250" /></div>

Code for session:

function set_session($username, $password) {

    $query = $this->query("SELECT * FROM ".DBTBLE." WHERE username='$username' AND password='$password'");

    ini_set("session.gc_maxlifetime", Session_Lifetime); 
    session_start();

    $_SESSION['first_name']    = $query['result']['first_name'];
    $_SESSION['last_name']     = $query['result']['last_name'];
    $_SESSION['email_address'] = $query['result']['email_address'];
    $_SESSION['username']      = $query['result']['username'];
    $_SESSION['info']          = $query['result']['info'];
    $_SESSION['user_level']    = $query['result']['user_level'];
    $_SESSION['password']      = $query['result']['password'];
    $_SESSION['avatar']        = $query['result']['avatar'];

}   

There was no feature for adding an avatar, so I added the show <div> function in the form, created a column in the database named avatar, and added $_SESSION['avatar'] = $query['result']['avatar'] but the default image isn't displaying, where did I go wrong? Except from avatar, rest all is been displayed.

Answer 1

src="<?php echo $_GET['avatar']; ?>"

should be:

src="<?php echo $_SESSION['avatar']; ?>"
