			$image = '<a href="'.$link.'" target="'.$target.'">'.$image.'</a>';

		// array, key index starts at 0
		$this->_images[] = $image;

	public function display() {
		// randomize the array by finding max
		$rand_int = mt_rand(0, count($this->_images)-1);

// Usage
// NOTE: You can put the class into a separate page, then include it
// start
$image = new random_images();
// example 1
$image->define_image("http://cdn.joomla.org/images/logo.png", 'testing j');
// lets add a mix of linked images
$image->define_image("http://drupal.org/sites/all/themes/bluebeach/logos/drupal.org.png", 'drupal', 'http://drupal.org');
// output
echo $image->display();
