title: Bootstrap carousel: Make download next image when using background-image on div instead of img
body: <p>Prequel: I am using Bootstrap Carousel . Since I want to use background-size: cover, I am using a div with background-image set, instead of the default .</p>
  
  <p>The issue: For some reason, the carousel doesn't seem to preload the next image. When I click next image, I can see the image being downloaded. Unfortunately, I think because of this lack of preloading the images aren't getting the right size (Set by JS) in some browsers: </p>
  
  <p>Anyway to make it preload all the images in the carousel?</p>
