title: Control Netscalers image lazy-loading
body: <p>Our site runs through Netscaler and we have the Lazy-loading of images activated. I'm trying to understand it's functionality and if it can be controlled in any way. For instance if specific images can be set to not lazy-load. But I can't find anything on the specific implementation of it, just articles describing how to activate it. </p>
  
  <p>If I understand it correctly it works like classic js-based lazyloading by converting imagetags by adding the class lazy and moving the src to data-original attribute. Then a javascript puts the correct src back when scrolled into view. But on what implementation is it based? Tried searching all loaded sources on lazy but can't find anything specific that seems to be connected to this behaviour.</p>
  
  <p>Does anyone know how the Nestcaler lazy-loading is implemented and if there are ways to control it? </p>
