Getting name of resized image from image library

[eluser]Thorpe Obazee[/eluser]
Anyway, I modified my code like this to get it. If anyone has a better way... don't hesitate :p

Code:

function _save_ad($ad_id = FALSE)
    {
        $ad_data = array(
            'title'           => $this->input->post('title'),
            'user_id'         => $this->session->userdata('user_id'),
            'cat_id'          => $this->input->post('cat'),
            'tags'            => $this->input->post('tags'),
            'price'           => $this->input->post('price'),
            'desc'            => $this->input->post('desc'),
            'floor_flat'      => $this->input->post('floor_flat'),
            'building'        => $this->input->post('building'),
            'street_district' => $this->input->post('street_district'),
            'zone'            => $this->input->post('zone'),
            'date_add'        => date("Y-m-d H:m:s")
        );
        if ($_FILES)
        {
            $ad_data['image'] = $this->file['file_name'];
            $ad_data['image_thumb'] = $this->file['raw_name'].'_thumb'.$this->file['file_ext'];
        }
        $this->ads_model->save_ad($ad_data, $ad_id);
        $this->session->set_flashdata('message', $this->lang->line('ad_saved'));
    }
