 Object result = ((JavascriptExecutor) driver).executeScript(
   "return arguments[0].complete && "+
   "typeof arguments[0].naturalWidth != \"undefined\" && "+
   "arguments[0].naturalWidth > 0", image);

    boolean loaded = false;
    if (result instanceof Boolean) {
      loaded = (Boolean) result;
      System.out.println(loaded);
    }

var req = new XMLHttpRequest();
req.open('get', document.getElementById('imageid').src, false);
req.send(null);
