I'm trying to serve an image from Play, where the image originates from Gravatar. This code doesn't seem to work, but the URL is correct.

gistfile1.scala

import play.api._
import play.api.mvc._
import play.api.libs.ws.WS
import play.api.libs.concurrent.Execution.Implicits._
import java.io.File
 
object Application extends Controller {
  
  def index(email: String) = Action {
    Async {
      WS.url("http://www.gravatar.com/avatar/" + hash(email) + "?s=32&r=pg&d=mm").withTimeout(5000).get
        .map(image => Ok(image.ahcResponse.getResponseBodyAsBytes()).as("image/jpg"))
        .recover {
          case error => 
            Ok.sendFile(content = new File("public/app/img/generic_user.png"), inline = true).as("image/png")
        }
    }
  }
  
}
