controller
<?php
if(!empty($_FILES))
$upload_image = array('1','2','3','4','5');
foreach($upload_image as $i) {
if(!empty($_FILES["hotel_img$i"]['name']))
{
$hotel_ID= 12;
$config['file_name'] = $this->session->userdata('user_id').'-'.$hotel_ID.'-'.time().$i;
$config['upload_path'] =realpath(APPPATH . '../img');
$config['allowed_types'] = 'gif|jpg|png|jpeg';

else
{
$file_data = $this->upload->data();
$image_data['img_url'] = $file_data['file_name'];
$image_data['img_size'] = $file_data['file_size'] * 1024;

Answer 1

try adding this to your config:
$config['create_thumb']

Answer 2

Seems to me that $file_data is always the same and probably contains an array with the other pictures as well. Now your code is saying for every picture resize $file_data and it only picks the first picture uploaded. Try print_r($file_data) because i guess that's what is causing the problem.
