Your Facebook photo alumn is never private

Regardless of your permission setting on your Facebook photo albums, they are all considered public. Each album is assigned an unique access link. It can be found at the bottom of the album page (the link is only visible to you). Don't think you set the photos are only viewed by you; then the rest of the world can't see it. Facebook has explicitly said in every album that "Share this album with anyone by sending them this public link: ...." Obviously your photos are viewable to non-facebook users, which means everyone. The link will look like this:

In the above example, l=abcdefghij, I believe, is sort of the public access ID. Without it, non-Facebook users cannot go in the album or see the photo. Therefore, don't casually distribute your album link to anyone. Without it, the link is difficult for human educated guess; possibly a hack program can. If you have ever published the link to someone else, you may consider to create a new album by transferring the existing photos to the new one and then delete the old album. The new album will be assigned a new public access ID. Such a way it may keep your photos more safer. As of this writing, there is still no guarantee to keep your photo on Facebook 100% private.
