If you have the javascript in your php file you can interject php syntax
just like html
ie. $.preloadImages("<?php echo $image_src; ?>", "img/
if your javascript is in a separate .js file you have two options
1. Change the javascript function to allow you to specify anything dynamic
(ie. the images that will need to be preloaded) in a parameter which you can
pass from your php file when you call the function using the method above
or
2. (Not Recommended) Set up your web server to run .js files through the PHP
parser. Then you can use php syntax in the .js files
