How did you get the pic uploaded onto your FB page??
If the pic is in your "pics folder" in your computer, you can just upload the pic directly to the BYC pic uploader...
Click on "Uploads" at the top of this page and select the "browse" option. You can then get the pictures from "My pictures" as long as you have it on your hard drive.
Another option is to open a Photobucket account, upload pics there, and then copy & paste to BYC.
