Uploading images in cloud9ide?

Anyone else can't upload via the drag and drop function images in clou9ide? The name o开发者_Go百科f the image appears in the file browser in the ide, but the image is broken (displays the broken image icon, in chrome). In fifrefox I get HTTP error [24]:500 not_defined callback is not defined0.1. Ive reported it has a bug to cloud9, but no response and not a lot of other people complaining about this issue. Anyone knows if I am doing something wrong?

The drag and drop now works (well on the paid version). It was a un-implemented option at the time.
