Is it this the right question?

Englishmen, 1 I need your help! :) Is it right question to ask in next the following context?

For example: I'm showing a photo to my friend. But I'm not shure if that the man on person in the photo is my friend. And So I'm asking my friend (I have two variants):

- Is it you in the photo? I prefer, Is that you in the photo?

or

- Are you in the photo?   This is also correct BUT it is better to use the first one because the first one is more polite because this question implies that you totally cannot recognized him at all.  It may be good or a bad thing depending on his mood.  The first question implies that the person looks like you but you are not sure.  Safer this way.

or something else...

Thank you, if you for reading this text and understanding what I am asking mean. :)

1.  This is very archaic way of saying.  Nowadays, it can be viewed as being racist especially when you don't belong to that racial group.  Use it with care.  For example, you can use this in the following scenario.  England is going to war.  The Queen of England can say, "Englishmen!  Do your duty to defend our island nation!"; or you can hear the American President say, "Fellow Americans..."

I understand what you are trying to say.  It is understood from context that you need help from English native speakers because your essay is written in English.
