For now, images have to be hosted elsewhere and embedded in comments. We recommend GIPHY and Imgur for hosting:
Use GIPHY if you have a GIF or video. Videos will be automatically converted to GIF format.
You can use Imgur for JPGs, PNGs, or GIFs.
Upload your image or GIF
Hover over the image, click the dropdown arrow, and go to "Get share links"*
Copy the link starting with https://i.imgur.com
If the URL for your image is:
https://i.imgur.com/a0QXJKR.gif
Then just use a line of HTML like this:
<img src="<https://i.imgur.com/a0QXJKR.gif>">
And it will post this in the discussions:
