title: NAO Robot Optimized access to images tutorial
body: <p>I was just wondering if anyone had used the "Optimized access to images" example from the tutorial section of the naoqi help pages?</p>

  <p>i can get the code to compile and create the module in naoqi but I am at a loss on how to use it. none of the functions are callable and the only instruction on how to use the module is: "To retrieve the images, subscribe as usual using a proxy to ALVideoDevice, and specify the framerate, resolution etc."</p>
  
  <p>All examples for retrieving images have the line: ALValue img = camProxy.getImageRemote(clientName); which does not seem to go through the optimization routine.</p>
  
  <p>my question is , how do i use the optimization module in my main c++ code?</p>
