AS3 - Bitmap screenshot of dragged image

Hi

I have an masked image that is externally loaded onto my stage that the user can drag and position.

I then need to be able to record or save where and how the user has positioned the image by either

-taking a bitmap copy of where the user has positioned the image (my first and easiest thought of how to do this)

-or is it possible to get X and Y co ordinates of where they have positioned it

I have a movie currently set up but when the user clicks 'save and continue' it takes a copy of the original position of the image - not from where you have last dragged it to, any ideas?

Full code and attached fla file below

Many thanks for any help in advance
