let grouparray = userGroupArray[indexPath.row]
let url = NSURL(string: grouparray.valueForKeyPath("image_thumbnail") as! String)!
let data = NSData(contentsOfURL:url)
cell.RightImage?.image = UIImage(data: data!)
This code i have used to get the image but i'm getting "unexpectedly found nil while unwrapping an Optional value" error.
