Have you tried using the search for this section? Many have asked that same question.

Answer 2

You need to use css, in css type:
body {
background-image: url("your image path");
}

One Note: local images dont work in sololearn just images from url, so if you wanna use your image from phone, you need to upload it to some cloud(like dropbox...) and use url.
