How can I include videos and pictures in posts?

I’ve seen you put images and Youtube videos in your posts. How do you do that?

I think if you just write the url it works

Try with html

I tried writing the URL of a video and it worked perfectly. Thank you.

If you want the video to come out bigger in your post, you can paste YouTube’s embed code (tick the “use old embed code” option) into your post instead.

Thank you @Simeon, I’ll try it next time.
