Hello!

Basically, you do < b > (without the spaces, if you want bold text) < img src="/api/util/ext/image?img=URL HERE" > for the images!

there's also more that you can do, like < a href="" > and < / a > for links and such, and also < br > for line breaks! There's SO many more that you can do, but those are the ones that I use the most. Oh, and also < i > for italics.
