I just uploaded a new imag w/thumbnail into my gallery (LittLeMisSaTTiTuDe 3),  it uploaded mine with my thumb nail just fine, and faster than usual, but it also created  a black square for  a thumb nail beside it, and when you clik on it you get the same image.  Can I delete this, without deleating the one with my thumbnail, or will it delete both images????  confused ain`t I???
