Am I able to add bones to a photo I have prepared in parts from Photoshop?

I use An quite allot and love it!

However of late I am wanting to develop my skills and start getting into more of it. Using bones the camera etc.

Now I don't draw anything in AN I do all my imagery in photoshop and save as psd then import to stage.

I mostly use artwork of friends - cut it up into parts to seperate all the bits I need for my animation.

Im wanting to speed up the process and use bones to tie in the characters etc.

At first when I try to add bones it says cannot add bones to bitmap image.

However when I highlight the peice and select "Break apart" it allows me to add bones.

But for some reason its not really working out right.

Is there a tutorial someone can direct me too that uses the bone tool feature on imagery not created in AN?

Thank you.
