Uploading and sharing photos with friends is a popular Facebook feature. The Facebook photo viewer displays low-resolution images for faster viewing, but the original picture file is made available for downloading purposes. The original picture file can be downloaded for editing, printing or backup needs.
Log in to your Facebook account.
Select the picture you wish to download from your personal photo album or from a friend's profile page.
Click on the thumbnail of the photo selected for download. The Facebook photo viewer appears.
Click the "Download" link located in the photo viewer.
Select "Save As" and click "OK" to initiate the picture file download to your computer.
If the picture file is a high-resolution photo, the "Download High Res" link appears in the photo viewer.
