No problem. We'll help wherever possible & I'm sure other readers of
this list are glad to hear such advice.

Look at src/example/gtk/tree/TreeExample. 

You can add multiple renderers to each column (as is done in the first
column of the example). If the first one you add is a
CellRendererPixbuf, then you should get your desired effect. 

You will have to (for now) store the names of the image to be displayed
at each node in one of the data blocks of the treestore and map this to
the renderer in the column using something like
myTreeColumn.addAttributeMapping( myPixbufRenderer,
CellRendererPixBuf.Attibute.PIXBUF, 1)

... but also very powerful. We should, probably, create more simple
wrapper classes, like SimpleList.
