친구분을 이라크 사진여행에 초대 합니다 'someone' invite you a photo exhibition about Iraq or 'someone' suggested a travel(or trip) to Iraq with your friend(or with you) for taking pictures I think... the former meaning is general.

친구분을 = to your friend 이라크 = Iraq 사진여행에 = travel photos 초대 합니다= invite So it merely like, "Invite your friend to take travel photos" ,,, something like that sorry, I'm not yet good in Korean :-)
