Modifying a Script

Hi, hopefully someone can help.

I found a script that can display a series of images by modifying the url. For example, if site.com/img[1021-1042].jpg was entered in the form, those images would all be displayed on one page. I have it modified so that if site.com/story.php?page=[1-4] is entered, pages 1-4 will display. The problem is that, in many cases, ?page=1 is the second page, and story.php is the first page.

The script is not advanced enough to list all the pages. So what I need to do is modify it so that I can display all the pages. In my opinion, the best way of doing that would be like this:

http://site.com/story.php | http://site.com/story.php?page=[1-4]

Code (markup):

That way, the first page is posted as long with the group of pages.

How can I change the following code to do that?
+Rep to anyone that helps.

    <SCRIPT LANGUAGE=javascript>
