title: Do image URLs in a Javascript array automatically get pre-loaded into the browser?
body: <p>I'm just looking for confirmation on an question I haven't seen directly answered.</p>
  
  <p>I am building a site and I'd like to load many image urls into a Javascript array without actually sending the images to the browser. To cut down on server bandwidth usage, I'd like to store the URLs in the document and only load them one at a time when the user takes a specific action to do so.</p>
  
  <p>I suppose my question is the opposite of the many "how do I use Javascript to pre-load an image" question like the one found <a href="https://stackoverflow.com/questions/476679/preloading-images-with-jquery/476681#476681">here</a>. The prevalence of these questions suggests that it's safe to stick the urls in a Javascript array at the top of the document and the browser will not automatically pre-load them. Is my assumption correct?</p>
