how create two content type?

Issue Summary

http://drupal.org/node/130517
here I read instructions for create multiple node profiles. But aren't clear some steps.

I would like create user with a content type Profile and a content type Images
and in form registration to have only Profile.
So when user make registration must fill only Profile node type and after in own account
can if want to fill the Image nodeprofile.

Question:
for to hawe this is necessary to have usernode acitvate?

how must to be set node family?
In the tutorial: Per default there is a link to each nodeprofile of a user on its usernode.
Seem that automatically usernode is connect at nodeprofile. So no one setting I must to do?

Or I must create 2 relations
Parent: usernode Child:Profile
Parent: usernode Child:Image ?

or
Parent: usernode Child:Profile
Parent: Profile Child:Image ?

or others?
