Add a picture to the fotografias on your perfil page. Once you do, click on the fotografias button on your perfil page, and look for the picture that you want. Once you find it, you'll see a small button that looks like a person. Click on that person and you'll have your perfil picture. As for background, this only works on clubes you've created. You need to click on the editar button, and go the Banner option, and select a picture to the ones you have saved and upload it to the banner. This also works for the clubes perfil picture as well, only smaller. I hope this all helps
