Java script modification question

I would like to have this part of a script grab the "pics" from a different Directory, so that I can run another version on a different page with different pics.

Sooo... how do I modify this to have it grab the pics from a Dir (such as Images)?

PHP:

<script language="javascript1.1">

today = new Date();
day = today.getDay();

arday = new Array("Sunday.jpg", "Monday.jpg", "Tuesday.jpg", "Wednesday.jpg", "Thursday.jpg", "Friday.jpg", "Saturday.jpg");

document.write("<img src='" + arday[day] + "'>");

</script><P>

 

Code:

document.write('<img src="Images/' + arday[day] + '">');

(assuming the Images folder is a subfolder of the current folder.)

 

Thanks!
