$this->session->userdata('image') 

is not set yet in $this->session->set_userdata($newdata);!

foreach($query->result() $rows)     {         //add data session         $newdata = array(                 'id'            => $rows->id,                 'memberfname'   => $rows->memberfname,                 'memberlname'   => $rows->memberlname,                 'email'         => $rows->email,                  'logged_in'     => true            );     } 

in $newdata should add 'image'
