You can display images by using IMG tags: [img*]http://image link here[/img] (remove the *)
I tried that amoung other variations, no good... for me at least.
You need to use the full `
.jpg` URL. I'll do it correctly below. I've append an lowercase `
L` to the image ID before the `
.jpg`-part as that returns a smaller image (courtesy of Imgur). I've also linked the full resolution images so that people can click on the image.
