MULTIPLE RANDOM IMAGES WITH LINKS AND TEXT

[robbyirish]

I need some help customising this code..  i know very little about javascript so im hoping you guys can help me out.

 

this script displays a random image with a link, i've customised it  so it displays the text at the bottom of the image as well by adding a new variable and including it in the document.write function

 

the problem i have is i have no idea how to make this script display more than one image at a time without dupicates. please help!!

 

heres the code

 

 

<script language="JavaScript">

 

function random_imglink(){

  var myimages=new Array()

 

  //random images below

  myimages[1]="image1.jpg"

  myimages[2]="image2.jpg"

  myimages[3]="image3.jpg"

 

  //corresponding links below

  var imagelinks=new Array()

  imagelinks[1]="image1 link"

  imagelinks[2]="image2 link"

  imagelinks[3]="image3 link"

 

  //corresponding text below

  var imagetext=new Array()

  imagetext[1]="this is number 1"

  imagetext[2]="this is number 2"

  imagetext[3]="this is number 3"

 

  var ry=Math.floor(Math.random()*myimages.length)

 

  if (ry==0)

    ry=1

    document.write('<a href='+'"'+imagelinks[ry]+'"'+'><img src="'+myimages[ry]+'" border=0><br>'+'"'+imagetext[ry]+'"'+'</a>')

   

}

 

  random_imglink()

</script>
