Hi Cat Run,
Go to the pulldown menu on the top right of the page (under your name and by the profile picture). Click on "My Account," and your blank picture space should be at the top of the page, with boxes for importing a photo from Facebook or adding from your computer.
Thank you Steve, that was so easy, I must be tired. Thanks for the info and have a great week.
Glad I could help. Yeah, it's easy, but it's not extremely obvious.
