A Rule to copy the user's picture
Install views rules module, make a views-rule of users, if you need UID as a contextual filer add it as always, then in middle column set your UID as an integer in parameters settings, add user pictures as a field, now in middle column settings, set user-pictures as an file entity. then in your rule, fetch entity by id with your variable UID, now you have user picture avilable and can be copied to your content type file field. Done, cheers.
