SMS Picture missing

Not sure if you're still having this problem but I had the same problem as well and figured it out recently. In order for your facebook contact pictures to be shown in the text message "conversations" you have to join the contact in your phone to the persons FB account. If you join the FB account to the persons phone number, the picture won't show up in text message conversations and will only show up in your contact list. Very very strange. Also, I didn't sync my contacts using the facebook app, it only worked with the social accounts feature on the phone. That's basically the short answer, if anyone needs more of an explanation let me know.
