nemanja?

"We missed you too. We want you to come here very much but my uncle says that your mom wouldn´t allow you. You grew up so much. Would you like me to send you a photo of mine ?"

Actually I made a mistake. benim fotomu must be the object of atmak because bakmak takes dative. But it doesn´t really make a difference in the meaning.

at|a|y|ım is subjunctive, nemanja. The voice of concepts envisaged by the speaker.

                           sg 1st atayım

                           sg 2nd atasın

                           sg 3rd ata

                           pl 1st atalım

                           pl 2nd atasınız

                           pl 3rd atalar

Only the 1st persons are used usually. They can often be translated with Let me or Let us. I have seen the 3rd person singular sometimes in poems and proverbs, so it is good to recognize it. In the above question I would translate it as shall I send  -  just like you did.
