title: Preload background images with jQuery?
body: <p>I have a div thats currently set to display none, The Div has a background image that is approx 5000px wide, 2000px high. </p>
  
  <p>I toggle the div display attirbute with jquery on a button click only with the image being so big the div loads and the image loads 1/2 seconds afterwards; is there a function where I can show a preloader until the image is ready and then display it?</p>
  
  <p>Thanks</p>
