How do I parent objects(animation frames) to an armature rig?

I have the skeleton mapped out on the character, but the hair, eyes, and hands have multiple hand drawn frames that I wish to animate. I tried doing standard parenting of layers (like the hair frame layers to the head) but when I move the rig, it doesn't move with it. I've been teaching myself how to use the program and I'm not sure what to do here, so any help would be appreciated. Thanks guys.
