Since your cover photo goes across the entire width of your timeline, the image you select for your cover has to be at least 720 pixels wide. This means you may not have the option to choose certain photos as your cover photo, or you may get an error if you try uploading a photo that isn’t big enough. If the photo you want to use is too small, try uploading the photo in high resolution, or choosing a different photo.

You can see all of your cover photos by clicking on the Photos box at the top of your timeline (under your cover photo) and finding the Timeline Cover Photos album.

Note: Like profile pictures, cover photos are all public. This means you won’t see an option to edit the privacy settings of your cover photo album.

If you add a cover photo to your timeline, it will be visible to the public, just like your profile pictures. This means that anyone can see your current cover photo and any other images you’ve used as a cover. So unlike most of your other photo albums, when you visit your Cover Photos album you won’t see an option to adjust the album privacy settings.

To edit your cover photo:

1. Go to your timeline
2. Hover over your cover photo
3. Click Change Cover at the bottom-right of your cover image
4. Pick one of the options from the pop-up menu (ex: upload a new photo, reposition your current cover photo, or delete your cover)
5. Save your changes

Your profile picture is the picture that friends see next to your name everywhere on the site. This is how people recognize you. Your cover is the large image at the top of your timeline. This is your chance to feature a unique image that represents who you are or what you care about.

Note: Like your profile pictures, cover images are public, which means anyone will be able to see them.

A cover is the larger photo at the top of your timeline, right above your profile picture. Note: Like your profile picture, cover images are public, which means anyone visiting your timeline will be able to see them.

We've found that people have a better experience viewing your timeline when they see a cover that is as unique and individualized as you are. This helps people learn more about you. It also helps us prevent spam, fake profiles, and other content that can detract from your experience on Facebook. An easy way to ensure your cover image is unique is to choose an image from your life, like a photo from a wedding, day at the beach, or birthday party. If you want to use a photo to show solidarity or express support for a cause or organization, you can still post a status or a photo and star it on your timeline.

To add a cover image to your timeline:

1. Go to your timeline
2. Click Add a Cover
3. Choose whether you want to upload a new photo or pick a photo from one of your existing photo albums
4. Once you choose a photo, you can reposition it by clicking on the image and dragging it up or down
5. Click Save
