Hi
@CharlotteE
There is nothing obvious to me to indicate that he is a fake. The quality of the image is poor because it is a highly compressed JPEG format, so details are unclear.
To me, it does not look precariously balanced and items in boxes are not uniformly weighed through the box either. So that does not seem off to me either.
The scenario also seems unlikely (I know you did not ask for that feedback).
If they were so inclined, a UPS or FedEx driver could take a picture of the box in place and then take the box—no need to edit a box in. That does not make sense in this day and age of security cameras to risk losing one's job for an uncertain reward in a random box (they don't know the contents).
It is quite possible it was taken after delivery by someone else (e.g., porch pirate). In many areas,that is quite common (I don't know about your location).
Note that with FedEx and UPS, if they deliver to a location different than the one directed by the customer, they typically take responsibility and cover the cost (or if from Amazon, Amazon will cover the cost).
It's just more likely someone took it after it was delivered.
I hope that helps and empathies to your neighbor. It is a violation of someone and almost uniformly creates some pretty bad feelings.
