There are thousands of ways to pose for a wedding picture. Yes, I really have seen them all. Work with the photographer in order to get your best angle.
And if you are the photographer, and you don't know, then give the money back and let the happy couple get someone else at the last minute to do their pictures. Seriously. The photographs and the rings are all that is left when a wedding is concluded and that means they need to be good. Wedding photography is not the same as vacation photography. It is a matter of lighting and timing and any wedding photographer worth more than two pennies will take hundreds of pictures during even the smallest wedding, and will then cull them down to the best 150 or so.
