      I dont quite get where your comming from, I think a differnt language or oop
      (short for oops)

      a variable does not have properties, it is not an object as in VB, java, and
      others...

      try
      $photo = "photo$i"; // just a little cleaner
      $photo_size = filesize($photo ); // if your wanting file size

          Or getimagesize() if you need to know the width and height
