Php in js - rollover path

i’m trying to make a site that has rollovers coded in javascript, but want to be able to have the path for the images stored in a variable ($images_path) so i can modify according to different folders/levels i’m in.
i’ve been running into several parse errors.

here’s what i tried with escape characters (lines 2-10 each onmouseover/down is its own line):

<?php
include
“<a href=”$pages_path/index.php"
onmouseover=“changeImages(‘about’, ‘$images_path/about_over.gif’); return true;”
onmouseout=“changeImages(‘about’, ‘$images_path/about.gif’); return true;”
onmousedown=“changeImages(‘about’, ‘$images_path/about_over.gif’); return true;”
onmouseup=“changeImages(‘about’, ‘$images_path/about_over.gif’); return true;”>
<img name=“about” src="$images_path/about.gif" width=“78” height=“22” border=“0” alt=""></a>"
?>

however, i get a parse error:

Parse error: parse error, unexpected T_LNUMBER in /home2/whatthe/public_html/work/sunfood/pages/menu.php on line 9

line 9 is the <img> tag. not too sure what is causing this or if this is even or if this can even work with php inside a javascript.
anyone have any idea if this will work or if there’s another work around to for this? thanks.
