Resolve relative path

[fanghanonline]

I use the plugin with Lazyvim. Configured as instructed in the readme.

• I use Chrome browser
• No problem rendering the rest of my Markdown document.
• Image with local path "../img/xxx.png" is not rendered.
• After changing the path to an path relative to "root", not the root of the my Ubuntu. The image got rendered.
• Pushed to GitHub and it resolves the "../img/xxx.png" but not the "relative to root" path

Possible solution:

1. follow the GitHub style, resolve the ".." from where the Markdown file is
