How to add png in markdown file?

[babahui]

Hi. I use a link in markdown file, as "![png][/assets/photoname.png]", and save the png file in /assets. But it doesn't work on website. Is there something wrong?
I just found it works when I change the link to "![png][https://username.github.com/repo/assets/name.png]", and can I just use relative path to do this work?

It works if you use parenthesis for the filename/path and not brackets. See example below. This is the normal syntax.

![png](/assets/photoname.png)
