Troy,
AFAIK, the only way to add images to a treeviw is to have an associated ImageList control. You can then use the LoadPicture function to access the file-based image and load it into the Imagelist. You can then set the Icon property of each treeview node. Rough example:

Imagelist Control
With THIS.ListImages
   .Add(,'Extension1', LoadPicture('MyPicture1.Bmp'))
   .Add(,'Extension2', LoadPicture('MyPicture2.Bmp'))
Endwith

Treeview Control
THIS.Imagelist = <object reference to Imagelist control>

THIS.Nodes.Add(,,'Root','Root','Extension1')

The Extension1 in the Nodes.Add call specifies the key of the image to use in the Imagelist control. You can also change the icon on-the-fly by getting an object reference to the Node in question and changing its Image property.

HTH.
