hi peeps

a mate just asked me to look at this code, i know the solution is probably very easy but i'm not particularly good with javascript so i though i'd post it here as one of you is bound to be able to eat it right up :)

its a simple exercise to create a manual (next/previous) slideshow...

Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
          "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html lang="en" xml:lang="en" xmlns="http://www.w3.org/1999/xhtml">
  <head>
    <meta http-equiv="Content-Type"
          content="text/html; charset=ISO-8859-1"/>
    <title>Ex6 Slideshow</title>
    <script type="text/javascript">
    var pic=new Array();
    pic[0]=new Image(); pic[0].src='imgs/R1.jpg'
    pic[1]=new Image(); pic[1].src='imgs/R2.jpg'
    pic[2]=new Image(); pic[2].src='imgs/R3.jpg'
    pic[3]=new Image(); pic[3].src='imgs/R4.jpg'
    pic[4]=new Image(); pic[4].src='imgs/R5.jpg'
    pic[5]=new Image(); pic[5].src='imgs/R6.jpg'
    pic[6]=new Image(); pic[6].src='imgs/R7.jpg'
    pic[7]=new Image(); pic[7].src='imgs/R8.jpg'
    pic[8]=new Image(); pic[8].src='imgs/R9.jpg'
    pic[9]=new Image(); pic[9].src='imgs/R10.jpg'
    var i=0; // current image

    function step(imgID)
    { i++
      if(i>9) { i=0 }
      document.getElementById(imgID).src = pic[i].src
    }
    </script>
  </head>
  <body>
    <h1>Ex6 Slideshow</h1>

    <p><img id="i01" src="imgs/R1.jpg" alt="image slideshow"
            height="612" width="459" /> <br/>
       <input type="button" value="Next" onclick="step("i01")"/>
       <input type="button" value="Previous" onclick="" />
    </p>
  </body>
</html>

i'm good enough to know it hasn't god a chance of working in its current form :p...

cheers :)
 
like i said it isnt my code, but my knowledge of js isnt good enough to get this working cuz at present when you press the buttons, nothing happens...
