How do I post an image?

Depends on where you want to post it. If you're trying post a pic on a comment: you can't. You can only post pics when replying in the Question area.

Can I ask how you do that?

While the front (main) page has questions: you can't post pics there. Usually, depending on how you access this site (tablet, mobile, computer) you'll see a list of topics (People Are Sharing) beside a comic and when you go there to answer one of those topics it gives you the ability to post a picture along with your answer. Additionally, you should be able to create a share topic and post a picture with it too. I've never done this, so I'm a little iffy on the exact details.

Ooooh thankyouuu
