how to protect...

[guabi]

I have different albums, how can i protect one of them (a personal album) that only show to certain peoples? (is that possbile to add a password to one of the album?)

You can set any album to be viewed by certain groups only.  So you can create a new group, add the people you want to view the album to that group, and set the album permissions accordingly.

ps, please only one question per thread.  Do not ask unrelated questions on threads, even if you started it.  I have split your posting accordingly.
