There is an issue on image path in markdown posts. We must use {{ site.baseurl }}/abs_path to link images, therefore we can’t see the images in our local markdown app.
Is there any solution to solve it?
No not that I know of. This is a known limitation. You can also host the image separately and link to it that will allow you to see it in markdown.
Either way you should try to preview your blog posts locally rather than the markdown editor. This will let you iterate faster and catch issues
