For the reception, this will depend mostly on the bride and groom. First of all... as many pictures as possible should be completed prior to the ceremony so that the guests are not waiting for pictures after the wedding. As soon as the ceremony is over the remaining pictures should be completed and done in (fingers crossed) less than an hour.

From there:

1) Wedding party introductions (can include parents)
2) Welcome
3) Dinner/Hors d'hoeurves
4) Cake / Toasts (should be done within 45 minutes of the introductions, even if guests are still eating)
5) First dance
6) Parents dance (father/bride mother/groom)
7) Bouquet and garter toss is usually near the end of the evening. (optional)
