title: Use jQuery to find all images on a (different) page via ajax for preloading
body: <p>I'm building a app - converted from flash to html/js and using jQuery. Pages/scenes are pulled in via ajax and I have a 'loading' overlay in place until these are loaded however in addition I want to preload images for the next and previous pages. </p>
  
  <p>So I pull in page-5.php via ajax then I need to preload the images in the background for pages 4/6 to speed things up for the user. </p>
  
  <p>I have a preload function I can insert an array of images into - the tricky bit is using ajax to find the src of all images on page-6.php for example.</p>
  
  <p>So I need a call to:
  - find all images on page-6.php, grab their src's into an array. 
  possible?</p>
  
  <p>I guess I could hide an array on each page containing the images and grab this but I'd rather keep it all dynamic.</p>
  
  <p>Any thoughts / help much appreciated.</p>
