OK - for albums....
If you make it "private" only your friends can see the pics (well, me too - BUT, you are posting on my servers about three feet from my desk, so I don't count
)...
"Public" means that ONLY folks registered to the PGCA Forum can see the entire album (just this community).. For folks not registered here - they can't see any Albums - public or private - and can only see the pics you choose to post in this thread as an embedded pic...
In other words - lets say you had a PIC you only wanted folks registered to the forum to see? Just include it in your album - and don't embed it into your post(s)...
Best to ya'..!
