First of all change the imagecopyresampled function to imagecopyresized function.
imagecopyresized($image_p, $img, 0, 0, 0, 0, $new_width,$new_height, $width, $height);
Than change the function from imagecreatefromgif to imagecreatefromjpeg because you are using jpg in if condition.And write the path below i have given like that.
move_uploaded_file($this->temp_path, imagejpeg($image_p,$target_path,100));
And sure to unlink if you don't than it will bring you two image files because you are using copy function be sure to unlink.
unlink($this->filename);
I have just done it. I hope it will work for you too.
