You may want to send that one off to Scout.
The technical wiki says that flat scans of US and other foreign currency are prohibited. A flat scan to me would be a perfect, horizontal shot of a bill that someone in theory could just go and print off on their super duper currency cloning machine.
The bills in your photo are all crooked, or partially hidden, so I don't think someone could suplement their savings account with those.

Same goes for the other photo you provided. It's not a perfectly flat horizontal shot.
Maybe it was an error, or maybe the Inspector was airing on the side of caution. Scout should be able to have a look and let you know if they are acceptable or not. Hope that helps.
