Placement of strumming hand

I'm confused about where to place my strumming hand. Should it rest behind the bridge, for example, when I pick? Or should I rest my ring and pinky fingers on the pick guard while I pick? How about when I do a full strum?

~Thanks~

This tutorial has a really thorough explanation on that topic:
