title: How to use KingFisher or AlamofireImage library with auth token?
body: <p>I have a tableView with customCells and I need to load pictures from a REST API (access with auth token).
  As Im a noob in swift I came across some libraries and it seems KingFisher or AlamofireImage are good ones for asynch loading and caching images retrieved from an API call. </p>
  
  <p>But since my API here has an access token, how can that being passed into this request?</p>
  
  <pre><code>//image handling with kingfisher
      if let imgView = cell.schoolCoverImage {
          imgView.kf_setImageWithURL(
              NSURL(string: "")!,
              placeholderImage: nil,
              optionsInfo: nil,
              progressBlock: nil,
              completionHandler: { (image, error, CacheType, imageURL) -&gt; () in
                  self.tableView.reloadRowsAtIndexPaths([indexPath], withRowAnimation: UITableViewRowAnimation.Automatic) }
          )
      }
  </code></pre>
  
  <p>For example in Alamofire there is the field headers where the access token can be passed</p>
  
  <pre><code> //Sample API call with Alamofire
    Alamofire.request(
          .GET,
          baseURL+schools+nonAcademicParameter,
          headers: accessToken
          )
          .responseJSON { response in
              switch response.result {
              case .Success(let value):
                  completionHandler(value, nil)
              case .Failure(let error):
                  completionHandler(nil, error)
              }
      }
  </code></pre>
  
  <p>But with AlamofireImage the field headers seems not to be available</p>
  
  <pre><code>//Image request with AlamofireImage
   Alamofire.request(
          .GET,
          "https://httpbin.org/image/png"),
      headers: ["Authorization" : "Bearer fbzi5u0f5kyajdcxrlnhl3zwl1t2wqaor"]  //not available
          .responseImage { response in
              debugPrint(response)
  
              print(response.request)
              print(response.response)
              debugPrint(response.result)
  
              if let image = response.result.value {
                  print("image downloaded: \(image)")
              }
      }
  </code></pre>
