Here's a worrying fact: your Facebook profile picture and cover photo are visible to anyone with an internet connection, unless you've set your profile to hidden.

Your profile picture is the square image that usually appears alongside your name on searches and on your profile page. Your cover photo, meanwhile, is the large image that sits at the top of your profile page.

And don't think you're safe just because you've set your photos as visible to friends only. Profile pictures and cover photos are set to public by default, meaning anyone can click on them for a larger version. They can also see any comments and likes.

This is great for someone looking to get back in contact with you, as it helps verify who you are. But some people may not like this – whether it’s for their personal privacy or because their kids are featured in the photos.

Facebook have already put in place new protections for people's profile pictures but the feature isn't available everywhere in the world. For now, you can follow the steps below to protect your profile picture and cover photo yourself, or watch the video.

Tip 1 – Set your Facebook profile to Private

If you’re worried about your privacy, then the best way to ensure your profile is locked tight is to set your entire profile to private – although people not already your friends will not be able to find you this way.

Go to the question mark icon situated at the top right and click Privacy shortcuts, followed by See More Settings.

Check that none of the sections are marked Everyone or Public in the third column – if they are, click on Edit at the end and set it to Friends or Friends of friends in the drop down box depending on what you want.

Tip 3: Choose an obscure photo

Alternatively, you could protect your privacy by using an obscure photo without faces, such as a photo of your feet in the sand on holiday or a photo of your garden that can’t identify you.

This can be done by hovering over your profile picture until you see Update Profile Picture.

Should you want to keep your profile picture, it’s worth locking it down.

You should be aware that a small thumbnail of your profile picture will remain visible but any comments and likes will be hidden.

To do this, find the question mark icon at the top right corner, followed by Privacy shortcuts, then See More Settings.

Tip 5: Securing your Cover photo

Your current Cover photo cannot be hidden and anyone can see it full-size alongside any comments.

But if you followed Tip 4, all your previous Cover photos will be set to friends only at least.

If you’re unhappy that you cannot hide your Cover photo from public view, you could also consider Tip 2 or Tip 3.

Tip 6: Previous profile photographs

Even if you have a private setting on your photos already, all previous profile pictures and cover photos can still be seen.

When carrying out Tip 4, all previous shared content, including profile pictures and Cover photos, will be set to friends-only, blocking anyone you’re not friends with from seeing them.
