Codeigniter Pass the serial number of current image - php

Question

I am using codeigniter. I have retrieved a array from my database. I need to pass the current number (Serial number) of image into the view so that I can display it in there.
Say, in the first page, I need to pass #1 so that it would let the user know that it is the first image. And say if they are visiting the 3rd image (array[2]) then it should display #3 .
Basically what I have is the option for the users to click next #4 and #2 previous to go through the images and I want to display the serial number of the current image in the page.
array(5) {
[0]=>
object(stdClass)#21 (6) {
["id"]=>
string(2) "17"
["gallery_id"]=>
string(1) "5"
["title"]=>
string(6) "sample"
["filename"]=>
string(12) "n9a67681.jpg"
["description"]=>
string(10) "sdhdfhafdj"
["created"]=>
string(19) "2013-06-29 08:25:56"

Controller:
$this->load->library('pagination');
$config['base_url'] = example.com/controller/action/uri_segment;
$config['total_rows'] = 5;
$config['per_page'] = 1;
$config['uri_segment'] = 3;
$this->pagination->initialize($config);
$position = ($this->uri->segment(3)) ? $this->uri->segment(3) : 0;
$data['links'] = $this->pagination->create_links();
$data['image'] = your_array[$position];
$this->load->view('your_view', $data);
Put in your view file "echo $links" (to create the next and previous link), and work as you want with your image informations.
