repostion first item to middle if start is middle

Hello guys , i made some modififiction i want to share with you but i dont know how to make a patch yet.

i worked on
; $Id: views_slideshow_imageflow.info,v 1.1.4.1 2010/04/16 16:59:58 aaron Exp $

i made a modification in file
theme/views_slideshow_imageflow.theme.inc

search for

/**
 *  We'll grab only the first image from each row.
 */
function template_preprocess_views_slideshow_imageflow(&$vars) {
  // Initialize our $images array.
  $vars['images'] = array();

  // Strip all images from the $rows created by the original view query.
  foreach($vars['rows'] as $item) {

and replace with

/**
 *  if postion is middle re order the first item to get it in middle
 */
function middle_reorder($array){

		$array =array_reverse($array);
	
		
		
		// newst always come last
		$lastmodifier = sizeof($array)-1;
		$middlemodifier= floor(sizeof($array)/2);
		$newwArray=array();
		
		// start check to build our new array order
		for($i=0; $i<sizeof($array); $i++){
			
			// if middle
			if($i==0){
				
				$newwArray[] = $array[$middlemodifier];
				
				}
				else
				{
						//if last
						if($i==$middlemodifier){
						$newwArray[] = $array[0];	
						}
						else
						{
							$newwArray[] = $array[$i];
						}
					
				}
			
			
		}// end loop


		return $newwArray;

}


/**
 *  We'll grab only the first image from each row.
 */
 
function template_preprocess_views_slideshow_imageflow(&$vars) {
	//print_r();
	
	$postion =$vars['view']->display['default']->display_options['style_options']['views_slideshow_imageflow']['start'];
	if($postion=='middle'){
	
	 $data = middle_reorder($vars['rows']);
		
	}else{
		$data =$vars['rows'];
	}
	
  // Initialize our $images array.
  $vars['images'] = array();
 //print_r($vars);
 //print_r('<br>----------flow test---------<br>');
  // Strip all images from the $rows created by the original view query.
  foreach($data as $item) {

this modification will take the newest item comes from the views and make it the middle one in condition you chooses to view the images as middle case.
