Videographers

My fiance and I really want our wedding guests to get to know each other. We've collected lots of pictures of them over the years, and now we want to put together a video or slide show that can be played during the wedding reception. How do we go about doing this?

Must videographers be included in the rehearsal dinner? The videographer wants to come to the rehearsal "because it is a new church for him and he wants to familiarize himself with it." He even told me he intends to bring his wife! We kind of think it's a blatant ploy for a free meal. What do you think?
