Hmm, the standard [image] for adding a link to an image ought to work anywhere that uses HTML. If you're using the Dreamwidth rich-text editor to post, you ought to be able to copy-paste the image in (or add an image already on the web by using the insert-image button) and then select the image and use the insert-URL button.

And now we'll see if I picked the right option to show HTML as code instead of interpreting it, or I have to edit it.

EDIT: I poked about for an easy way to make code display as code, but no luck. I'll just message it to you on Discord. x_x
