When चित्रो are released, Summit hardly notifies anyone. लोल However, we do have one official (well, two if आप count Bella's hand with feathers) चित्र that was revealed in EW last month.
This is the only चित्र (minus the picture from Bill Condon's twitter) that has been released from the movie. Other चित्रो are probably manips.
Again, when they release photos, they hardly ever announce that they are releasing चित्रो unless it's for promotion. If आप are talking about the teaser posters, they probably will announce it. Summit loves to make a huge fiasco about posters या trailers haha It'd actually be kind of cool if they had a mini trailer for the superbowl या something :P
But anyways, we won't see any चित्रो of Breaking Dawn unless 1) Summit tells us (which is rare), 2) they're leaked (which is not impossible), या 3) for promotional reasons. However, I'm sure they will release some soon. They still have about 3 months til BD wrap, but I know they know प्रशंसकों are itching for something.
However, I'm sure द्वारा summer, we'll have a teaser trailer. I'm thinking May. Possibly April. Rob's Water for Elephants movie is in theatres in April. I wouldn't be surprised if Summit tried to promote BD then.
Sorry, off topic. Answer to your question. No, we do not know when official Breaking Dawn चित्रो will be released. We only know of one (possibly two if आप count the Twitpic) official चित्रो and that's from EW. :) Hope this helped!
