Clean up dynamically created 'html elements' on page?
<p>I have javascript showing results from a search, and when the users click 'more' - more results are added, so on average there can be up to 1,000 results displayed on a session, with each result having 20kb images, so after about 100 results you can start to see the page get slower.</p>

<p>The images are currently the background of a div, and when I clear the background the page is still slow. So is it the 1000+divs that are making it slow, or the large array in javascript memory? or has the image just not been cleared correctly?</p>

<p>Is there a proper way to destroy something efficently with javascript?  (other than $(this).html()?)</p>
