Go to your profile page.

At the top where your name is displayed there will be an edit icon. Click that.

Then tap the Avatar option on the left.

Select "upload an avatar" and chose the image you want from your computer.

Once you finish uploading/adjusting it select "save, I'm done" to lock in your changes.

That's it :) Just remember the same image will be displayed on all Wikis you're a part of.
