As far as I tried, a file path like this would work

![encoded-jwt](/home/username//technical_writing/encoded-jwt3.png)

but these following relative path would not:

![encoded-jwt](encoded-jwt3.png)

or

![encoded-jwt](./encoded-jwt3.png)

although this image file sits along with my markdown file.

Hope relative file path is supported, and thanks so much for your awesome work!
