how do I make a facebook profile picture unviewable?

[yo mama]

I have pictures of when i was younger and more immature in my facebook profile pictures album. some of my friends have commented on them. I would like to take them down but I don't want to loose the comments that were made or the people who "liked" them. Is there any way to "archive" these pictures so that no one else sees them but me, and to repost them if I wanted to? Thanks for your input, much appreciated

Go to the album, click Edit Album and modify the Privacy settings.

Although you may have to create a 'safety list' to whom the album will be viewable.
