The images not showing up on windows servers.

[zzm88]

I used the django tag {{ node.content |emoji_replace_unicode}} , it renders well and turns out <img src="/static/emoji/img/unamused.png" alt="😒" title="unamused" class="emoji"> But the corresponding unamused.png is not showing up. And it seems that that file is just some string linked to a real png file rather than a real image. How to redirect this "/static/emoji/img/unamused.png" to the real one?
