I added in css in the custom css section of the profile settings!! Here's the snippet of code if you want :D put in your image url inside the brackets of url(). And you can change the position by changing the px of the "bottom" and "left" attributes too. "transform" will change the size of the image. Feel free to send another question if there's something you don't understand or if you're not sure how to change something specific!!

.profile_container::after{ bottom: 215px; left: -610px; height: 0px; transform: scale(.15); z-index: 999 !important; position: absolute !important; content: url() !important; }
