No, JS cannot access any of the files or directories it sits with on
the server.
I don't believe that. You can't get a directory listing, easily, but you
*do* have access to any file that is in the same domain as long as the
server doesn't prohibit access. If JS couldn't access them, AJAX would
be a totally dead technology.
These are different things. Yes, AJAX can acess files back at the
server, but it has to name them specifically. You can not scan a
directory and retrieve the listing with JS.
You probably can use an artifice,
if access to the folder is allowed you can try to open this folder in an
iframe or a popup, then to analyze links listed in this window via DOM
and to extract paths of images to display them somewhere.
This is counting on the server to list the contents of the directory if
there is no index file. Also, you would have to change your script for
every server.

Images on a remote server that you control should be trivial with PHP:
<?php
$localPath = '/usr/home/public_html/images';
$remotePath = 'http://yousite.com/images';
$fileList = '';
echo "<script language=\"JavaScript\" type=\"text/javascript\">\n";
echo "var remotePath = \"$remotePath\"";
echo "var imageFilenamesArr = new Array ("
if (is_dir($localPath)) {
if ($dh = opendir($localPath)) {
while (($file = readdir($dh)) !== false) {
$fileList .= "\"$file\",";
}
closedir($dh);
$fileList = substr($fileList, 0, strlen($fileList) - 1); // Remove the
final comma.
}
}
echo ");\n"
echo "</script>";
?>
That's just a draft, but the idea is that you can use PHP to generate your
JavaScript, and basically initialize variables that require some sort of data
from the server side environment. Its a simple, non-AJAXian solution to the
problem. If you're running 5.2.0, you could easily do this with JSON to, but
without the need to do complex XMLHttpRequest calls.
On a server-side file, you _shouldn't_ be able to access it directly with
JavaScript.
