This may seem like a silly thing to make a forum about, but I have actually found quite a lot of people who don't know how. And if you're only new to this site then I suppose this will be helpful.

If you're on a tablet tap your name, and if your on the computer hover the mouse over you're name and a list should come up, click avatar.

When you do the screen below will come up, if you tap choose file you can pick a photo that you have saved on your computer, or you can use a URL to pick a photo.

Don't know what a URL is? Press Here
