Add a picture to the 照片 on your 个人资料 page. Once 你 do, click on the 照片 button on your 个人资料 page, and look for the picture that 你 want. Once 你 find it, you'll see a small button that looks like a person. Click on that person and you'll have your 个人资料 picture. As for background, this only works on 俱乐部 you've created. 你 need to click on the 编辑 button, and go the Banner option, and select a picture to the ones 你 have saved and 上传 it to the banner. This also works for the 俱乐部 个人资料 picture as well, only smaller. I hope this all helps
