I have update the repo and add support for jsBin : https://github.com/agusputra/nodebb-plugin-jsfiddle
It seems the plugin is not working for me.
So when creating new topic/reply and I click "picture" in the composer, the image will not open in a lightbox.. I need to go back and forth to see another image
And if by "upload image", the image will open in a lightbox, but at first it will open in a new tab.
I install the plugin via ACP.
