How to show img tag from GitHub markdown in Hugo

Issue #788

I just convert my blog https://onmyway133.com/ from Hexo.js back to Hugo again. Hugo now uses goldmark as the default markdown processor instead of blackfriday

All works well, except that I use GitHub markdown to write articles, which use raw HTML img tag for uploaded images. Hugo works well with ![]() syntax but it ignores img tag

The solution is to tell goldmark to accept raw HTML. Put this at root level in config.yaml in your Hugo website

markup:
  goldmark:
    renderer:
      unsafe: true
