How do you insert an image to the Github README, so that it shows up when loading a Github page that uses the README as the source?
I have written this code in my README:
<img src="https://github.com/my_username/xxx/blob/master/image.jpeg" width="1000"/>
When I look at the README in the repository, the image shows up. However, when I open my Github page (which uses the Jekyll theme), the picture shows up as a broken image symbol.
I would much appreciate some guidance! Thanks :)
As shown here, try instead to place your image in another folder (not something with an _ underscore). Create /assets/images/
in the root of your project and place the image there.
Then in your README.md, you can reference it with either HTML or Markdown

(to avoid putting all images in the same folder, see the jekyll-postfiles plugin)
Check that is displays in both GitHub and GitHub pages after Jekyll processed your project.
