Oh! It's actually pretty simple! You see, you can upload images to a website designed for link inserts. I would use FileGarden, It's more dependable and permanent than other websites! (Just making an account is the real hassle!) There’s a button in the profile customization that has a little image icon, and you can insert an image's link. If you wanna get a link, just hold the image and select "open image in new tab" then copy the link in that separate tab and paste it in the artfight bio! I can create a more easier tutorial if you like. And in order to make banners on the sides, there's a little button with tiny blue lines and a green plus! It'll give you rows to center your images!
