Stray Cat, you've done a pretty good job of proving that it is the same image!
What details are you claiming don't line up? Using your animation I checked the base of her nose, the edges of the eyes, the three central frills on her cap, the bottom of the tie (if that's what it is), the folds of her dress round her waist and the shadow caused by these folds, and (following Pythra's observation) the full outline of the wedge-shaped shadow next to her right sleeve. The positions all match almost perfectly, except for the tip of the cap frill to her left (which is very blurred in the copy).
What is the probability, do you think, of all these matches happening independently - head and body angles, frills, folds and shadows (including details such as the waist shadow and the wedge-shaped shadow above being cut off in the same place by the right sleeve)?
I'd say the correspondence is so striking that it has to be the same image (or another one taken within a few seconds, which seems far less likely).
Pythra, it's not a belt - it's a shadow caused by her blouse overhanging her skirt where it's tucked in at the waist. It's obvious that the image of the child can't be on top of the railings.
