สอบถามเกี่ยวกับการอัพโหลดรูปภาพครับ เกี่ยวกับการเช็คจากค่า height กับ weight อ่ะครับ

$images = $_FILES["fileUpload"]["tmp_name"];
			$new_images = "".$_SESSION['user_id']."_".$_FILES["fileUpload"]["name"];
			$DirPath = "images\image\ " . $new_images . "";
			$DesPath = $_SERVER["DOCUMENT_ROOT"]."/".$DirPath;
			//copy($_FILES["fileUpload"]["tmp_name"],"images/image/".$_FILES["fileUpload"]["name"]);
			$width=600; //*** Fix Width & Heigh (Autน caculate) ***//
			$size=GetimageSize($images);
			$height=900;//round($width*$size[1]/$size[0]);
			$images_orig = ImageCreateFromJPEG($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,"images/image/".$new_images);
	    	ImageDestroy($images_orig);
			ImageDestroy($images_fin);
		
			$table = "tb_photo_salon";
			mysql_query("SET NAMES UTF8");
	
			$filename =$HTTP_POST_FILES['files']['name'];
			$filetempname =$HTTP_POST_FILES['files']['tmp_name'];
			$filesize =$HTTP_POST_FILES['files']['size'];
			
			$data = array(
				"ref_id"=>addslashes($_SESSION['id_id']),
				"name_image"=>addslashes($new_images),
				"date"=>addslashes(date("Y-m-d H:i:s")),
			);
			insert($table,$data);
			header("Refresh:0;url=upload.php");
