Engagement Photo Ideas: I especially like that it is in Black and White. This might also work with a faded 60s color overlay, but I think Black and White brings an intimacy to the image that can't be matched. I think the roles should be reversed though. A woman's body is better suited for the lower image and the man's over the upper image kneeling in almost a worshipful pose.
A trick for hanging photo collections: Lay out your arrangement. Flip frames over. Lay waxed paper on top of frames. Mark hanger/nail spot on waxed paper. Flip waxed paper over and tape to wall, nail into wall where indicated. Tear down waxed paper. Hang photos.
