Digital Photo Collage at Wedding

Is it worth taking the time to put together a photo collage of family/friends pictures that will be streaming on the TVs in the room outside of our reception? Early arrivals to the ceremony will be in the room beforehand and it will be the spillover for those wanting to sit inside during the cocktail hour (or if there is GASP rain).

Have any Larkfield brides taken advantage of those TVs before to display images? If so, how did it go?

Thanks!!!!!
