It sounds like you have something like this:
Is the image a URL (
https://image_here.jpg)? Or just a bare image filename (
GitHub will need the image to be a URL pointing to a publicly hosted image, or you can include the image in your repository and use a relative path that way (put the image under the
images/ folder of your project, then specify the image as
images/image_here.jpg) … Or you can start drafting a comment somewhere on a GitHub issue or Pull Request, add an image to your comment, and copy the URL that GitHub uses to host said image and paste that into your markdown file.
I hope that helps, let me know if it doesn’t and I’ll try to help figure it out.
