Test it by simply dragging out a contact, dragging it back in and when the Address Book pops up the "duplicate message" window click the "review duplicate" button and then the "keep both" button.
When I did this before messing with the pref's as above, the imported contacts had no photos. After messing with the pref's as above, the imported contacts were indistinguishable from the originals.
I'm fairly certain that it's a problem with the pref's. If tweaking the pref's as above doesn't solve the problem then remove the com.apple.AddressBook.plist file from your ~/Library/Preferences folder and then re-do your preferences in the Address Book app.
