Saving Portion of screen as image

I need some pointing in the right direction. I am developing a costume design ap where you drag movieclips of a costume onto a model. The model is made up of movieclips (head, torso, feet etc) that move to a frame depending on what costume piece is dropped on it so it looks like it is wearing the costume peice. This is all fine…
HOWEVER…
I have been asked to add a function where you can email the full costume to yourself. How can I save part all the movieclips that make up the model as a bitmap or save as image on a server to be accessed later. I could probably contain all the movieclips into on if muliple mc’s as image is the hangup.

Examples:
artpad.art.com/artpad/painter/
or
www.flashpaint.com

ps-I don’t need the recording fuction on these sites but if you know that, I would love a hint in that direction too

Thanks
