You need to use the ImageList as you have been. Add resources to image list and then use its index in treeview.

Hi,

assume the below tree structure
- Root
      - Red
      - Blue
      - Yellow

and set the images to the treenodes as like below in your code
'create an ImageList and add the images from the resource files
Dim tvImageList As New ImageList
tvImageList.Images.Add(My.Resources.Red) ' Red.png
tvImageList.Images.Add(My.Resources.Blue) ' Blue.png
tvImageList.Images.Add(My.Resources.Yellow) ' Yellow.png

' Set the imagelist to the treeview
mnuTreeView.ImageList = tvImageList

mnuTreeView.ExpandAll()

'nodRoot - Root Node's name
'nodRed - Red Node's name
'nodBlue - Blue Node's name
'nodYellow - Yellow Node's name

' set the ImageIndex value for the nodes you wanted like below
mnuTreeView.Nodes("nodRoot").ImageIndex = -1 : mnuTreeView.Nodes("nodRoot").SelectedImageIndex = -1

mnuTreeView.Nodes("nodRoot").Nodes("nodRed").ImageIndex = 0 : mnuTreeView.Nodes("nodRoot").Nodes("nodRed").SelectedImageIndex = 0
mnuTreeView.Nodes("nodRoot").Nodes("nodBlue").ImageIndex = 1 : mnuTreeView.Nodes("nodRoot").Nodes("nodBlue").SelectedImageIndex = 1
mnuTreeView.Nodes("nodRoot").Nodes("nodYellow").ImageIndex = 2 : mnuTreeView.Nodes("nodRoot").Nodes("nodYellow").SelectedImageIndex = 2
