Enabling user to choose image from webserver folder to display

I have a large number of archived images in a public folder on the web server. I want the user to be able to browse a list of the image files by filename and select one to be displayed.  This needs to be done using client-side JavaScript code only (no server-side code).

Basically I want to be able to populate a SELECT tag with the filenames of all files in the webserver folder.

What is the easiest way to do this?

Thanks

The client can not access the server's files. Just imagine the havoc if any javascript could read any server. If you want to publish that sort of information, you would have to use a server-side script. For example, in php, you could do this

<select name="picture">
<?php
$files1 = scandir("/usr/local/files/pictures/");
foreach ($files1 as $f)
   print "<option value='$f'>$f</option>\n";
?>
</select>

Thanks, I understand the security concerns but was assuming that as I can browse the folder concerned by putting the URL in the web browser (it is in a public area of the web site) it should be possible to read the contents of the index somehow and parse it to get an array of filenames using only client-side code.  If not I'll have to try and get php enabled on the server.

You might be able to do it if you are running apache and you have autoindex turned on. What happens when you browse to the directory that contains the images?

It displays the directory. I think I can get php enabled so I'll accept your php snippet as a solution and build on that. Thanks.
