Dr. Awkward said:Either that, or they figured that the dragonborn resemble tieflings enough that they can pass for them, and since dragonborn are the mystery race, they weren't about to label the picture "Dragonborn Warlock". The reason that the pictures exist in the first place may be because someone thought it would be clever to hide them in plain sight, to reduce the chance of leaks. They can always just say, "no, no, that's a tiefling, not whatever it was you thought."
That's been my working theory, and still is.
