I want to share pictures between my wife and me, on an external USB drive. The OS is ubuntu 12.04. The drive is a Western Digital 500 GB and sudo blkid /dev/sdc1 return LABEL="My Book" UUID="9389-61cd" TYP="vfat"
ls -l /media return drwx------ ted ted 32768 Dec 31 1969 My Book
(Ted is my account, and the account used to install Ubuntu 11.10, and upgrade to 12.04)
I want the access to be open to, at least, a common group, so preferred is drwxrwxrwx
This should automatically mount this way.

debdoesn't have too much access to files owned byted. – Ignacio Vazquez-Abrams Aug 19 '12 at 22:37
