    Slideshow viewable by multiple users in real time

    Hi,

    i have been working on a jquery slideshow that automatically loads an image from a given directory. The slideshow starts by itself but you can stop it and manually view one image after other by pressing next and previous buttons. What i want to do now is to make it interactive so all the visitors seeing it can see it run as i press the buttons back and forward and see what i see in real time.

    This is the code:

    PHP Code:
    <!DOCTYPE html>
    <html>
    <head>
      <meta http-equiv="content-type" content="text/html; charset=UTF-8">
      <title> galeria</title>
      <script type='text/javascript' src='jquery.js'></script>
      <style type='text/css'>
        html {background-color:black;}
        #fader {
        margin: 0 auto; 
        width: 1610px;
        height: 400px;
        border:1px solid red;
        display:block;
        overflow:hide;
        }
       #fader * {display:block;}
     .button {
        background-color:gold;
        width: 50px;
        height: 30px;
        font-size: 20px;
        line-height: 30px;
        text-align: center;
        position: absolute;
        top: 30px;
        display:block;
        cursor:pointer;  
       }
      #next {
        right: 850px;
        top:420px;    
       }
      #prev {
        left: 840px;
        top:420px;   
       }
      #pause {
        left: 900px;
        top:420px;
        color:orange;
       }
     #inicio {
        left: 960px;
        top:420px;
        color:green;  
       }
      </style>
     <script type='text/javascript'>//<![CDATA[ 
    $(window).load(function(){
    $(function() {
        $('#fader *:not(:first)').hide();
        $('#fader img').css('height', '100%');
        $('#fader img').css('margin', '0 auto');
        $('#fader *').each(function() {
            var img = $(this);
            $('<img>').attr('src', $(this).attr('src')).load(function() {

            });
        });

        var pause = false;
        
        function fadeNext() {
            $('#fader *').first().fadeOut().appendTo($('#fader'));
            $('#fader *').first().fadeIn();
        }

        function fadePrev() {
            $('#fader *').first().fadeOut();
            $('#fader *').last().prependTo($('#fader')).fadeIn();
        }

        $('#fader, #next').click(function() {
            fadeNext();
        });

        $('#prev').click(function() {
            fadePrev();
        });

        $('#pause').click(function() {
            pause = true;
        });

       $('#inicio').click(function() {
            pause = false;
        });

        function doRotate() {
            if(!pause) {
                fadeNext();
            }    
        }  
        var rotate = setInterval(doRotate, 10000);
    });
    });//]]>
    </script>
    </head>
    <body>
    <?php
    function scd($dir){$files=scandir($dir);sort($files);reset($files);return $files;}
    $output='<div id="fader">';
    $dir='imagenes';
    $files=scd($dir);

    foreach(
    $files as $file){
    if(
    $file==='.'||$file==='..'){continue;}
    if (
    strpos($file,'.flv') == false) {
    $output.='<img src="'.$dir.'/'.$file.'" alt="">';
    }
    else {
    $output.=<<<EOF
    <iframe src="$dir/$file" style="height:100%;width:100%"></iframe>
    EOF;
    }
    }
    echo 
    $output.'</div>';
    ?>
     <div class="button" id="next">►►</div>
     <div class="button" id="pause">▌▌</div>
    <div class="button" id="inicio">►</div>
     <div class="button" id="prev">◄◄</div>


    </body>
    </html>
    I wonder if this is possible by using AJAX or json, rather than resorting to more complicated stuff such as java.

    Thank you.
