//upload single file
 		if($_FILES['fileupload']['error']==0)
		 { 
		 //Type Allow
			if((($_FILES['fileupload']['type']=="image/pjpeg")
				||($_FILES['fileupload']['type']=="image/jpg")
				||($_FILES['fileupload']['type']=="image/gif")
				||($_FILES['fileupload']['type']=="image/png"))
				&&($_FILES['fileupload']['size']<200000)) //1kb=1mb
		{
		//upload & Resize
			if(trim($_FILES["fileUpload"]["tmp_name"]) != "")
				{
					$rand=time();
					$images = $_FILES["fileupload"]["tmp_name"];
					$new_images = "Thumbnail_".$_FILES["fileupload"]["name"];
					move_uploaded_file($_FILES["fileupload"]["tmp_name"],"../uploads/product/".$_FILES["fileupload"]["name"]); -->  บรรทัดนี้ได้ครับ
					$width=106; //*** Fix Width & Heigh (Autu caculate) ***//
					$size=GetimageSize($images);
					$height=round($width*$size[1]/$size[0]);
					$images_orig = ImageCreateFromJPEG($images);-->เขียนแบบนี้ได้ป่าว
					$images_orig = ImageCreateFromPNG($images);-->เขียนแบบนี้ได้ป่าว
					$images_orig = ImageCreateFromGIF($images);-->เขียนแบบนี้ได้ป่าว
					$photoX = ImagesX($images_orig);
					$photoY = ImagesY($images_orig);
					$images_fin = ImageCreateTrueColor($width, $height);
					$img=$rand."_".$images;
					ImageCopyResampled($images_fin, $images_orig, 0, 0, 0, 0, $width+1, $height+1, $photoX, $photoY);
					ImageJPEG($images_fin,"../uploads/product/".$new_images); -->  บรรทัดนี้ ไม่ถูกอัพโหลดเลยครับ  
					ImageDestroy($images_orig);
					ImageDestroy($images_fin);
