I'm assuming that the index would point to the same imagelist as that used for the display icon of the node but this seems not to be the case.
Furthermore I'm guessing that provided I could get this function to work the icon at the index would be overlayed on the main Icon. Sort of like the short cut overlay icon.
Am I right in my assumptions and can some one show me how to use the property.
Can you please verify that this is still an issue If so, let me know and I'll find someone to provide help.
