need help to finish a loop

I am new in JS.
I need a loop to show 200 pictures to replace code like below:

leftrightslide[0]= '<img src="images/1.jpg" border=1>'
leftrightslide[1]= '<img src="images/2.jpg" border=1>'
...
leftrightslide[199]= '<img src="images/200.jpg" border=1>'

How to use for loop to do the job?

for (i = 0; i <200; i++){

...

}

 

for (var i = 0; i < leftrightslide.length; i++)
{
    document.write(leftrightslide[i] + '<br />');
}

Code (javascript):

 

Thank you. But your code did not change image file name as 1.jpg, 2.jpg...200.jpg.

 

for(x=0; x<200; x++) {
document.write(leftrightside[x+1]);
}

 

^^ That'd skip the first image since it starts from 1.

I've tested my code and it works for me.

EDIT:

This is how I tested it.

<script type="text/javascript">

leftrightslide = new Array();

leftrightslide[0]= '<img src="images/1.jpg" border=1>';
leftrightslide[1]= '<img src="images/2.jpg" border=1>';
leftrightslide[2]= '<img src="images/1.jpg" border=1>';
leftrightslide[3]= '<img src="images/2.jpg" border=1>';
leftrightslide[4]= '<img src="images/1.jpg" border=1>';
leftrightslide[5]= '<img src="images/2.jpg" border=1>';

for (var i = 0; i < leftrightslide.length; i++)
{
    document.write(leftrightslide[i] + '<br />');
}

</script>

Code (javascript):

 

Actually, you can leave the array out at all.

<script type="text/javascript">

for (var i = 0; i < 200; i++)
{
    document.write('<img src="images/'+ i +'.jpg" border="1"><br />');
}

</script>

Code (javascript):

 

for(i=0; i<leftrightside.length; i++) {
document.write(leftrightside[i+1]);
}

is better.
