This is the only sane way to work. Running script as root or changing
permissions recursivelly to 777 is very strange at best (make all images
executable?). Files should have mode 664 (or 660 if not public).

However, since the default mask is 022 not 002, this requires some tweaks
to the environment.  I.e. in all your scripts do "umask 2;", in all user
shells (/etc/csh.cshrc, /etc/profile) add "umask 2", configure all
daemons (ftpd, sshd, apache) to use umask 2 as well. Then the directories
with mode 2775 will be automagically shareable for all group members.

Unfortunately, in the real world most of the sysadmins are lazy enough
(or not knowledgeble) to define a proper environment for their users.
They just give the root password to everyone, or periodically chmod 777
when a user calls.
