Hi all

I have a simple list of images here that are floated horizontally off the right of the page.

http://www.ttmt.org.uk/forum/gallery/

I can view the image by mouse scrolling left and right.

How can I scroll the page by moving the mouse left and right without scrolling.

So the gallery position will be determined by the position of the mouse on the page.

Code:
<!DOCTYPE html>
<html>
  <head>
  <title>Title of the document</title>
  
  <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js"></script>

    	margin-right:-20000px;
    }
    ul#gallery li{
      display:inline;
    }
    ul#gallery li img{
