Stupidity: Steve Trevor is the leader of a group of Allied spies, and they are traveling with a gorgeous woman who has shown to have amazing fighting skills and super powers, but they allow a group photo to be taken with Diana in her armor. They don't know who is taking the photograph nor what they intend to do with it. Their photograph circulating through a news publication or passed on to an enemy's intelligence service could compromise himself and the rest of his team, and they would absolutely know that. Undercover agents do not pose for photographs.
Wonder Woman (2017)
1 stupidity
Directed by: Patty Jenkins
Starring: Chris Pine, Robin Wright, Connie Nielsen, Gal Gadot
Continuity mistake: At the end after the massive explosion on the runway, two German soldiers get up unscathed and remove their gas masks. They suddenly appeared, as no one else was there, only Diana, and they are only a few feet away from the crater.
Diana Prince: You're a man...
Steve Trevor: Yeah... I mean... do I not look like one?
Trivia: There is a reference to the "Superman and Wonder Woman" comic book #226 when Diana is trying on an outfit with the same number.
Question: If Amazons are immortal and never age then how can Diana grow up there?
Answer: It would be more accurate to say they grow to a certain age then stop aging. Similar to the elves in Tolkien's Lord of the Rings.
Answer: They may never grow old, but they are not immortal since we see some die.
Answer: Diana is unlike the other Amazon women, so her physiology differs. In mythology, Amazon women were demigods - half human and half god. Diana's mother, Hippolyta, crafted her from clay and Zeus gave her life. Diana grew from an infant into adulthood, then, like the other Amazons, becomes either immortal or long-lived.
Answer: Thank you both.
Suggested correction: The photographer is not a reporter, he is one of the villagers. The photo was not taken to be circulated through print media, it was taken by the villagers to commemorate the day they were liberated. There only appears to be one copy of the photograph (which Bruce Wayne finds and sends to Diana), so the likelihood of it falling into the German's hands is incredibly slim.

It does not matter who took the photograph or why, or what he chooses to do with it. Undercover agents do not pose for photographs.
