2. Click on the word "Profile" that can be found at the top left of the page. This will bring you to your personal profile page. Several tabs including "Wall," "Photos," "Info" and "Boxes" appear under your name.

3. Click on the tab "Photos" just below your name. Your photo albums will be visible once the page loads.

There may be more than one series of numbers in the URL. Find the set that follows "id=". This is your FaceBook ID. Please note that the FaceBook ID is a digit-only number.
