After trying to make work-arounds for 4 hours, I found out that this problem was allready fixed by the creator by request on the post below. (Joomla should get an update notification feature :-)
I like this plug-in because it is no-nonsense, light and very easy to visually tweak through CSS. The FTP layer is an incredible improvement.
I do have one feature-request:
It would be very nice to have an editor button to insert the code. So n00b-users can easily select the right folder in images/stories. Even cooler (and quicker) would be to also manage the file upload through that button. So users can choose an existing folder or upload images to a new one.
