title: start to preload content after a complete page load
body: <p>i am trying to make the preloading work in such a way that the components i wish to preload start to load after successfully loading the page.</p>
  
  <p>for example,
  i have index.php. i want it to load up completely.
  as soon as it loads up i want to start loading the other components.</p>
  
  <p>to make things clear. i have a nav that makes use of large size images. if i load them along with the index.php file, it would increase load up time of the page. i wish for those large images to load after completely rendering index.php?</p>
  
  <p>am i making sense? is it possible?</p>
