Random homepage image generator is being defeated by Drupal's caching.

In my theme folder, I have created page-front.tpl.php
in the header, i have the following code ...
for background random_img.php is a class that checks a directory. the method randomImgs loads all files of a specified type (jpg), shuffles them, then returns a specified number of results (1). this processing is being defeated by caching
<?php
require("sites/all/themes/theme_name/includes/random_img.php");
$di = new DirectoryItems('sites/all/themes/theme_name/imgs/home_page_headers/');
$filearray = $di->randomImgs("jpg", 1);
foreach($filearray as $key=>$value){
print "<style> #homepage_photo {background: url(/sites/all/themes/theme_name/imgs/home_page_headers/$value.jpg) no-repeat black;} </style>";
}
?>the above code works fine when caching is turned off. I realize i could probably do this via a block, but I would rather have the image be the background of a div AND I figure this would be a good learning opportunity for me to gain insight from those who are more savvy then myself.
I attempted putting this code in my phptemplate_preprocess() function in the theme.php file with the same results... works when i'm not caching, but once i log out or turn caching on, it sticks to one result. I am new to working with preprocess functions so i'm guessing this method may have been way off.
I appreciate and thank you for any input!

You could try JQuery (javascript) or
stop the home page being cached with the CachExclude module

cacheexclude did the trick!
Thanks for the heads up!
