File Grabber with Random Photo Display

Looks in any directory you specify and gets all the files with extensions given by you. Returns them as an array that you can do anything with, I used it to pick four photos from the photo album directory at random (sort of random) and display them in the footer of a page. Works around open_basedir restrictions.

<?

var $files;

// the class uses extensions like ("jpg","gif","png")
// the function prepends the document root, so 
// give directory information like "/images/album"

	$files = array();
