I have used it few months ago and I guess this was then older version of this plugin. It worked with post. I did not find any code line where I enable post or something like that. Maybe in new version it is something differrent.

Edit:
Just took a look at the chrome console, when I upload it writes :

Failed to load resource

and on the right side the url to the upload function.

But it still works strange
