i have re tag the link and untill now i havend yet gotten the image host to work
[ img ] image link here
[ /img ]
and use something different than discord as your image host, it dosn's work like that, it for just showing a picture and discussion in current time. Discord just show directly from your computer. Instead use something like https://imgur.com/
(Imgure is the easy one, of course you can also use the forums own wiki page as a host, but for just showing of a drawing now and then, imgure is easier and faster)
to use Imgure:
1. log in
2. click on you'r name up in the right corner
3. click on "Posts"
4. pull the image directly from you'r computer into Imgure web-page, by holding down left mouse button and drag the file over to the web page and drop it.
5. Give it a few seconds.
6. hold your mouse over the picture, two icons will pop up in the upper right corner
7. click on the icon with three dots, it will expand
8. click "Get share links"
9. Select copy link on: BBcode (Forums)
10. Right click and past it in your post on the forum and post.
