function displayPicture() question

[Pr1nnyraid]

Hey guys, I'm trying to make a function that will display a group of similarly named images. So far my js looks like this, the script is awful but the general idea is still present. I want the titles to display in order from 1 to 21. title1.jpg ,title2.jpg, title3.jpg , etc.
Is this even possible? or are there any better ways to accomplish this?
I've never done this before but i do know some javascript.
Thanks for all the responses in advance. You guys are geniuses.

<script type="text/javascript">
function displayPicture()
{
      var imgNum ="title"+""+".jpg"+"<br />"
      var imgMax = 21
      if imgNum < imgMax,imgNum++,
      <img src = imgNum height="" width=''">
}
</script>

There are n no. of ways to do this. The way you have specified. It's a method we can do. But your code should be tuned.

<script type="text/javascript">
function displayPicture()
{
var imgStr="";
var imgMax = 21
for(var i=1;i<-imgMax;i++)
  imgStr+="<img src='title"+i+".jpg' height='' width='' /> <br/>";
}
</script>

hmmm the code is still broken....and my validator isn't returning any errors
I made one change to the function you provided, because title's are inside another directory called "maps".... I'm not sure if the root file should be included or not
<img src='maps/title"+i...

 
<script type="text/javascript">
  function displayPicture()
   {
   var imgStr="";
   var imgMax = 21
   for(var i=1;i<-imgMax;i++)
   imgStr+="<img src='maps/tit"+i+".jpg' height='200' width='200' /> <br/>";
   }
   </script>

@Pr1nnyraid
should be

 <script type="text/javascript">
function displayPicture()
{
    var i, imgStr = "",
        imgMax = 21;
    for (i = 1; i <= imgMax; i++) {
        imgStr += "<img src='maps/tit" + i + ".jpg' height='200' width='200' /> <br/>";
    }
    return imgStr;
}
// somewhere else
// container is the element, where the image string should be pasted
 container.innerHTML = displayPicture();
</script>

Yep Dormilich, It's a typography error. It wont happen again.

I fixed almost immediately after my second post. It works great now.At first I didn't think to add in another variable "i" but Ramanan cleared that up. Everytime I post here I'm always surprised at the quick responses and the level of programming skill you guys have.
