title: javascript preloader/progress/percentage
body: <p>I'm having trouble finding any good information on how to make a javascript(or jquery) progress bar WITH text that tells you the percentage.</p>
  
  <p>I don't want a plug in, I just want to know how it works so that I can adapt it to what I need. How do you preload images and get a variable for the number of images that are preloaded. Also, how do you change html/css and-or call a function, based on the number of images that are loaded already?</p>
