  <a href="http://www.dynamicdrive.com/style/csslibrary/item/css-image-gallery/" rel="nofollow">http://www.dynamicdrive.com/style/csslibrary/item/css-image-gallery/</a>
  to create a pop up image hover effect that I am dynamically generating with php. I have one problem with this technique that every single image is downloaded when the page loads. How can I have css only download the image on hover.?
  Right now css is pushing the images off the screen when the page loads (left: -1000px;) then brings them back into view on hover.Is it possible with css to accomplish this then what other choices do I have?</p>
