php อยากจะ resize ภาพ แล้วลบ delete ภาพต้นฉบับ ทำอย่างไร หามาหลายวันแล้ว

if(trim($_FILES["filUpload"]["tmp_name"]) != "")
			{
			$images = $_FILES["filUpload"]["tmp_name"];
			$fileName = date("YmdHis")."_".$_FILES["filUpload"]["name"];
			//$new_images = "Thumbnails_".$_FILES["filUpload"]["name"];
			copy($_FILES["filUpload"]["tmp_name"],"Myfile/".$_FILES["filUpload"]["name"]); //!  บรรทัดนี้เอาออก
			$width=570; //*** Fix Width & Heigh (Autu caculate) ***//
			$size=GetimageSize($images);
			$height=round($width*$size[1]/$size[0]);
			if($size[2] == 1) {
			$images_orig = imagecreatefromgif($images); //resize รูปประเภท GIF
			} else if($size[2] == 2) {
			$images_orig = imagecreatefromjpeg($images); //resize รูปประเภท JPEG
			}
			// $images_orig = ImageCreateFromJPEG($images);
			$photoX = ImagesX($images_orig);
			$photoY = ImagesY($images_orig);
			$images_fin = ImageCreateTrueColor($width, $height);
			ImageCopyResampled($images_fin, $images_orig, 0, 0, 0, 0, $width+1, $height+1, $photoX, $photoY);
			ImageJPEG($images_fin,"Myfile/".$fileName);
			//ImageJPEG($images_fin,"Myfile/".$new_images);
			ImageDestroy($images_orig);
			ImageDestroy($images_fin);
			@unlink("Myfile/".$images_orig);
			}
			// if(copy($_FILES["filUpload"]["tmp_name"],"myfile/".$_FILES["filUpload"]["name"]))
			{
