I am able to find the response data in array but not able to download and populate in Collection View. I have tried to upload the image from the image container from application but not able to download and upload by API

**Code**

```
    func get_data_from_url(){

    //API calls
    let url = NSURL(string: "http://android.eposapi.co.uk/?app_id=A1A2A3A4&app_key=K1K2K3K4&request=gallery")

    let request = NSMutableURLRequest(URL: url!)
    request.HTTPMethod = "POST"
    let postString = "gallery"
    request.HTTPBody = postString.dataUsingEncoding(NSUTF8StringEncoding)
    let task = NSURLSession.sharedSession().dataTaskWithRequest(request){
        data,response,error in

        if error != nil{
            print("error=\(error)")
            return
        }
        //Print out response object
        print("response= \(response)")
        //print response body
       // let responseString = NSString(data: data!, encoding: NSUTF8StringEncoding)

       // print("response data = \(responseString!)")

        var json: NSArray!
        do {
            json = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions()) as? NSArray
            print(json)
            print(json[0])

        } catch {
            print(error)
        }

        dispatch_async(dispatch_get_main_queue()) {
            self.collectionView!.reloadData()
        }

    }
    task.resume()

override func viewDidLoad() {
    super.viewDidLoad()
    get_data_from_url()

    self.collectionView!.registerClass(UICollectionViewCell.self, forCellWithReuseIdentifier: reuseIdentifier)

}

    override func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCellWithReuseIdentifier("cell", forIndexPath: indexPath) as UICollectionViewCell

    // Configure the cell
let image = cell.viewWithTag(1) as! UIImageView

    image.image = images[indexPath.row]

return cell
}

```

Tell me any one solution how to download images of anytype (either png or jpg) and populate in the `UICollectionView` using `mutable urlRequest`/
