title: Where to find jstree jquery plugin images?
body: <p>I'm trying out jstree, the jquery plugin to create a treeview. It works fine, but I can't get some of the inner workings of it. And one (seemingly) simple thing bothers me like crazy: Where do the images for the folder icons etc come from? I mean, even if I don't define a theme there are still default icons for the folders in the result. And if I change the theme to, say, apple, the icons change. But I have no idea where these images come from. I would have expected to find references to them in the theme css files, but I don't.</p>
  
  <p>If anyone can explain this, and preferably point me to them and how to reference and change them I would be grateful! Specifically, I want to be able to change the icons so that there is one icon for a closed folder and another one for an open folder.</p>
