How can I get the name of an Image of a certain treeItem in a tree.
For an item that gets selected I want to verify if a centain image with a
specific name was set?

You could use TreeItem.setData(key, value) to store the image name when
setting the image so that you can compare later on using
TreeItem.getData(key).

Perfect.

As I never used this. What is the normal usage for this function? Must I
see it as an enhanced option to "tag" an item with objects...

It is just a simple mechanism to associate data with a widget. For example,
if I have a Tree representing files and directories in the file system I
might associate a Java File object with each item in the Tree. The Tree
displays the name and icon for the file but if I want access to more
information about the file, I get the associated File object.
