JavaScript Bs_Tree example 4

tree similar to example 1. the special things here are:

using selfmade icons. this is done by just setting another image dir. the images in this new dir are all named the same way.
you don't see lines because the line-images in this dir are empty.
this example does not draw the tree into a div after the page loaded (with an onLoad code) as most other examples do it). Though this way of doing it is not recommended.
