How do I upload a profile picture?

😕 I set up my profile on this forum ages ago... but I still can't figure out how to actually add a profile picture like everyone else. Can I just upload one directly from my PC, or do I have to use an image hosting site like Imgur first, which is what I've seen people mentioning in other threads? 🤷
Someone please help me out here. 😉
Thanks.

There’s a Reddit thread out there with all the instructions you'll need for using the forum. It also includes this post.
