Woman looking at the private part of a man

Q:

1. If a woman looks at the private parts of a man without lust, does it establish hurmat-e-musaaharat?

2. A woman looks at the private part of a man in a picture or an image and feels lust, but she does not know whose private part this is. She does not know with whom she has established hurmat-e-musaaharat. Now if she is about to marry a man, should she doubt that those private parts may be of her future father in law and the groom is haram for her to marry. As she does not know with whom she has established hurmat-e-musaharat, what should she do?

Looking at photos

Q:

1. I wanted to ask whether it is sinful to look at photographs? Or can we can look at photos of our mahrams?

2. We are not allowed to look at non mahrams. Does it mean that we cannot look at him even at a glance for once? For eg. We need to see for once, so as to know who is our brother in law, or neighbour, uncle i.e. just for recoginition purposes.
