This is a simple PHP script to take a bunch of images in a directory and create and xml file that lists them. I use this script to help create my image gallery's in flash.

<?php
$file_dir="images/flash_gallery"; //change this to a folder name containing images
$omit_chars=0; //how many characters to cut off the title's front used if you want to number the images for the ordered the will play
echo '<?xml version="1.0" encoding="utf-8" standalone="yes"?>'; // echo out our xml doc type
echo '<images>'; // echo out image tag
			$dir=opendir($file_dir); // open the directory we sepcified earlier
			$xml_string= array(); // declare the  the array we will use to store the data to echo out for the xml file
				while ($file=readdir($dir)){ // read in the files from the directory we opened
					if(substr($file, -3) == "jpg" || substr($file, -4) == "jpeg" ){ // check to see what the file extention is
					$length = strlen($file) - 4; // trim the file extention off
					$caption = substr($file, 0, $length); // make the file name the caption for the image
					$tmp_str = '<pic> <image>'.$file_dir.'/'.$file.'</image>'.'<caption>'.$caption.'</caption> </pic>'; // create the xml
					array_push($xml_string, $tmp_str); // add the xml to the array
					} // end if				
				} // end while loop
				sort($xml_string); // sore the array
				for($i=0; $i<count($xml_string); $i++){ // loop use to echo out the $xml_string array
					print $xml_string[$i]; // echo current line of the array
				} // end for
closedir($dir); // close the directory we opened up earlier.
echo '</images>'; // close the images tag we echoed out earlier.
?>

This script opens the specified directory and searches that directory for JPEG images. It then outputs the contents of the directory in XML so all you need to do call the file containing script and process the XML with Action Script to make your image gallery.
