If you would use postimages.org you would have a direct link to just copy/paste to share here for the markdown format.

See the little square box on top of the post box that is explaining how to post images here. https://docs.github.com/en/get-started/writing-on-github/getting-started-with-writing-and-formatting-on-github/basic-writing-and-formatting-syntax#images

Put a nice interesting title and inside the text box paste the markdown link.
