if (!USER_ID) cpg_die(ERROR, 'Your message to invite visitors to register to see the big pic', __FILE__, __LINE__);
is given somewhere else in the forum to allow only registered users to view full-size pictures. I would like to know how to only allow users of specific user groups to do so.

unfortunately, I could not find an answer in the link you provided.
I tried using:
if ($USER_GROUP != 'Known Users' or 'Administrators') cpg_die(ERROR, 'You need to have at least Known User status to see the big picture.', __FILE__, __LINE__);
and I do have both of these group names in effect. The result is that the error is thrown for everyone. What am I doing wrong?
