Loading a Random Image into flash using php

Hello there,

I’m having trouble loading in my random images into flash.
I’m using this tutorial: http://www.kirupa.com/web/random_image.php

This is how I’m loading the php page into flash:

The activity viewer says the file (header_images_array.php) is loading in fine,
but the loaded images don’t appear in the flash movie.

This is the php page code:
$file_array = array
$total = count($file_array);
$random = (mt_rand()%$total);
$file = “$file_array[$random]”;
print("<img src=$file></a>");

Can anyone give me some thoughts on this?
