1) Use the XML HTTP Request object available in IE and Gecko-based browsers to
do a HEAD request for the file. The headers that get returned should contain
the file size (Content-Length) <url:

2) If you have any sort of server-side technology available to you (ASP, JSP,
Perl, PHP, etc), you could use it to retrieve the size of the file and then
"pass" that value to the client-side JavaScript:

<?php
# use PHP to determine the size of the file
?>
<script type="text/javascript">
var fileSize = <?php echo $fileSize ?>;
</script>
