Internet way: Okay, so, you go to whatever image you want on the internet. I press and hold since I'm on mobile, but if you are on a computer, then you right click. Then you open image in a new tab, then copy the url code in the address bar. There should be a image thing in the editor when you change your bio. Press/click it and then paste your image into the text box. If that doesn't work, then uh...I'm sorry.
