I had a quick look at your most recent reviews. None of those photos are a problem as far as I can see. In fact, your buyers are willing to not only leave a review but also take the time to snap a photo and send it as well. Why would you not want to keep them? Future buyers are getting a 'in-real-life' display example, and they will understand that a buyer's photo isn't going to be the same 'professional' standard as yours.
