We've all heard the horror stories about people who have been fired, or dumped, after an embarrassing photo or video came to light on Facebook. You can avoid this problem by restricting who can view photos stored on your profile, and even who can view photos in which you've been tagged – even if that picture appears on someone else's profile page. To manage this, click on the Account tab, choose "Privacy Settings", then "Profile Information". Navigate to "Photos and videos of me" – select "Only Me" from the drop-down list if you don't want anybody, apart from yourself, to see pictures and videos you've been tagged in; even if you're less concerned about incriminating material, it's wise to restrict this content to certain groups, such as the "Close friends" group you created earlier. You can also restrict access to every photo album associated with your profile: below "Photos and videos of me" is "Photo albums"; click on this to choose exactly which groups of contacts can view which sets of pictures.
