Best thing is first to save it to your computer and then upload it.
If you're on a PC, right click on the picture, choose to save the image, and save it to your computer. (I'm not sure how you do it on a mac, maybe just grab it and drag it to your desktop; you can also use that method on a PC).
Then in the top right menu of BYC choose My Profile, and on the left side under the avatar image click on "Replace Avatar", then "browse computer", find it on your computer, and click submit.
There's also a tutorial on this page:
