I had trouble with it to but I eventually figured it out. I have a Mac, so the file load is diffrent from PC. So I might not be able to help you there. But if you do have a Mac, load the picture off of the internet and put it into a named section in iPhotos. Then just log on, go to change avatar, and look up the photo section name in your Finder. Like I said, I don't work PC. Good Luck!
