Why Doesn't My Display Picture Show in Facebook?
The Facebook profile picture is often the first thing that visitors notice when they come to your page. Your picture also helps old friends and acquaintances to find your page and connect with you. If your profile picture is not showing up, you could be missing many valuable connections. The most common reason for a profile picture not showing is a Facebook bug. These bugs will usually be corrected and will not require any action from you. The display picture may also not come up because it wasn't uploaded and selected correctly.
Upload your profile picture. Log into your Facebook profile. Select "Edit My Profile." Click "Profile Picture." Select "Choose File." Select your profile picture in the browser window, and click "Open." The picture is now set as your profile picture.
Make your album picture your profile picture. Click "Photos" on your Facebook page. Click on an album. Double-click on a picture. Choose "Make Profile Picture" underneath the photo.
