Answer 1

Try this
if ($_FILES['vimage']['size'] > 0) {
$this->load->library('upload');
$this->upload->initialize($this->set_upload_options());
$this->upload->do_upload();
$fileName = $_FILES['vimage']['name'];
private function set_upload_options()
{
// upload an image options
$config = array();
$config['upload_path'] = './upload/'; //give the path to upload the image in folder
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '0';
$config['overwrite'] = FALSE;
return $config;
}

Try this
if (!empty($_FILES['vimage']))
{
$config['upload_path'] = './uploads/';
//$config['max_size'] = '102400';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['overwrite'] = FALSE;
$config['remove_spaces'] = TRUE;
$config['encrypt_name'] = TRUE;
$this->load->library('upload', $config);
$this->upload->initialize($config);
if (!$this->upload->do_upload('vimage'))
{
$this->session->set_flashdata('error', $this->upload->display_errors());
//redirect('controller/method');
}
else
{
$this->session->set_flashdata('success', 'Image Has been Uploaded');
//redirect('controller/method');
$img = $data['file_name'];
}
}

Please check first,
print_r(_FILES);
If you get files array then you can use below code for uploading image.
function do_upload()
{
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '100';
$config['max_width'] = '1024';
$config['max_height'] = '768';
// You can give Image formats if you want to upload any video file.
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload())
{
$error = array('error' = $this->upload->display_errors());
// uploading failed. $error will holds the errors.
}
else
{
$data = array('upload_data' => $this->upload->data());
// uploading successfull, now do your further actions
}
}

I have added your code in my system it's working for fine for me.
public function add(){
$this->load->library('upload');
$this->load->helper('form');
$this->load->helper('url');
print_r($_FILES);die;
$this->form_validation->set_rules('title','Title','required');
$this->form_validation->set_rules('description','Description','required');
if ($_FILES['pro_image']['size'] > 0) {
$this->upload->initialize(array(
"upload_path" => './uploads/',
"overwrite" => FALSE,
"encrypt_name" => TRUE,
"remove_spaces" => TRUE,
"allowed_types" => "gif|jpg|png|jpeg",
));
if (!$this->upload->do_upload('vimage')) {
$this->upload->display_errors();
}
$data = $this->upload->data();
echo 'img : '.$img = $data['file_name'];
}
exit;
if($this->form_validation->run()==FALSE){
echo '<div class="alert alert-dismissable alert-danger"><button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button><small>'. validation_errors().'</small></div>';
}
else {
$title = $this->input->post('title');
$description = $this->input->post('description');
$artist_dir = $this->input->post('artist_dir');
$highlight = $this->input->post('highlight');
$this->promotions_model->add_item($title, $description,$artist_dir,$highlight);
}
}
