first of all I want to thank the author for this great plugin, it seems very promising.
I would like to create my own scripts. I'm mostly familiar with JS and just a little bit VBS (actually I know only VBA, but they are similar).
The problem is that I don't understand the concept of this plugin

Is it possible to get any other information than a files properties? For example the width (in pixels) of an image file or the duration (in seconds) of an audio file?
