Guys this is really confussing, I asked one of the DV consultant here in nepal when I recived the 1st letter for help. they just said one photo is enough.
Now after I have visited the site I am more confused, the link says
"Two (2) photographs of yourself and of each family member applying for a diversity immigrant visa. Ensure that the photos comply with the General Photo Requirements."
I clearly doesn't say any thing regarding in which state we need to give them two photoes
@KS156 and @madu12 I don't know which one of you are correct or wrong

???
I hope me sending 1 photo doesn't effect my chance of getting the second letter.
