Pictures synchronisation google / facebook

Hi,

I would like to have the pictures of my contacts shown on my cellphone (samsung galaxy s plus).

I use the following method:

Edit google contacts (on pc) -> add url -> link to fb account of the contact example: https://www.facebook.com/firstname.lastname

Sometimes it works and the fb profile picture is loaded.

But often he profile picture doesn't show altough I can click " facebook profile view profile" in the contact data on my phone.

sometimes the phone takes the google+ profile picture.

In one occasion i loaded a profile picture manually, it appears in the contact list on the cellphone but not in the text messages menu. When i select view contact in the text messages menu i go to the contact list, where the picture is visible.

and in one other occasion a contact has a name and picture in the messages menu but isn't available in the contact list on the cellphone.

I just don't get it ...

Can anyone help?
