I hope this isn't too off-topic, but... I'm new here, and I absolutely love wallhaven, and for me it's when you're uploading your logo/avatar that you find out whether a website is decent or not. (Right after trying to scale the HTML "text area" component horizontally) Basically, I'm happy I can use transparent avatar. I wonder why is it that websites such as google (services) or youtube can't bother to implement it. Google even goes as far as to put round borders around your avatar. I then spend 10 minutes on editing my avatar so it's in center of the circle-shaped border.
But this is awesome! :) Can any web designer tell me how difficult is it to implement transparent avatars onto a site, and what issues can it cause, downsides it has?
