I want to know the answer to the following question:
In which year did the Synod of Constantinople confirm the veneration of images of Mary?
All the background I'm provided with is that "Both Roman Catholic and Orthodox Christians venerate images and icons of Mary, given that the Second Council of Nicaea in 787 permitted their veneration with the understanding that those who venerate the image are venerating the reality of the person it represents, and the 842 Synod of Constantinople confirming the same.". Is that enough to answer the question?
Answer: yes
