A simple question - How do I convert
var image1, image2, image3, image4
To a for loop that changes the variable name so I don't have to list them,
Like
for (var i = 1; i <= 4; i++) {
var image??
}
Thanks for the help.

Not quite sure what you're asking for....
<html>
<head>
<title>varImage.htm</title>
<script type="text/javascript">
var image1 = "a.gif";
var image2 = "b.gif";
var image3 = "c.gif";
var image4 = "d.gif";
// To a for loop that changes the variable name so I don't have to list
them,
for (var i=1; i<5; i++) {
alert(eval("image" + i));
}
// eval() is evil ...

Thanks for the quick response. At this point I'm just trying to declare the
variables image1, image2, image3, etc. for use later in the script, rather
than typing var image1, image2, . . ., image 20, image21, etc. The "image" +
i code is getting close, I think. Hope this helps to clarify.

What!!!
As you said eval() is evil... then why use it!
You can reference the var like this
window["image" + n].src

Then use this...

Sorry I meant :
window["image" + i] = "whatever.jpg";
alert( image0 );

If you have any serious number of such variables, you should probably
just use an array:
var image = [];
To a for loop that changes the variable name so I don't have to list them,
Like
for (var i = 1; i <= 4; i++) {
image[i] = ...
}

Thanks everyone for the help. I have it working. The array suggestion was
great since I do have a lot, hence the for loop coding.
