You can use the complete property to check if the image has finished loading. However, I think there are other issues with your code, mainly you are repeatedly loading the same image. Instead, you should load it only once and then check the complete property in an interval.

Something like this should work:

function LoadImage()
{
  x = document.getElementById("stream");    
  x.src = "http://IP:PORT/jpg/image.jpg" + "?" + escape(new Date());
  x.style.visibility = 'hidden';
}

function CheckIsLoaded() {
  x = document.getElementById("stream");    
  if (x.complete) x.style.visibility = 'visible';
}

function onStartLiveBtnClick()
{       
  LoadImage();
  intervalID = setInterval(CheckIsLoaded, 0);
}
