As always -- Thank you, Mysterious.  The screen captures are great.
Cousin Barnabas, since I am not one to shy-away from spoilers, I looked closely at the photo you warned us about on page 44 of Fangoria.  Of course I won't disclose information about the photo here, but I personally would not consider that much of a spoiler.  A predictable plot-point, maybe -- but not an important spoiler.  I can't imagine anyone looking at that photo and being shocked.  Most importantly, as you mentioned -- we don't even know the context of that photo.  Whether is occurs near the beginning, middle, or end of the movie.  We don't even know what in which time period it occurs -- 1700s or 1970.  At least, I could not tell.  
I'm not trying to get a discussion of the spoiler content of the photo started here, because I know that belongs in another thread.  I just wanted to comment that I sorta disagree with you, that the photo reveals a huge or surprising spoiler.  You're not wrong.  But, it's all a matter of perception, I suppose.
