Back when GeoSpy was available for everyone to use, I did a test where I just uploaded an image that had a black background and white text saying the location of a place and a textual description.
GeoSpy told me that it was the place mentioned in the picture, with the textual description as evidence.
Yes, I have done the same and also used it to prompt inject to give some info about the prompt, but I don’t have that data anymore.
