Live-Profile and User photo integration?

Hi All - I'm trying to have a user's photo in the sys_user table update their photo in the live_profile table.

1) Is this not OOB? (I.e, do I need to write a biz rule for it?)

2) (potential) biz rule:

when sys_user photo updated;

get image and

insert it in associated live_profile field.

Anyone have any tips from doing this before? Any cautions?
