You need to store the pictures (icons) in an Image list and associate it witht he menu bar. Add the Image list to your form (its not visible @ run time) and right click/properties to add your icons (give them a key for easy ref. and make note of the image number) and close. Add tool bar, right click/properties. Now add the imagelist to the imagelist box in the form you are staring at. There will only be one in the drop down, presuming you only added one ImageList. Click buttons/add button and add the image number in the image number box (the image number was given when you added each icon to the imagelist).
You can change this programatically too, as follows:
Private Sub Toolbar1_ButtonClick(ByVal Button As MSComctlLib.Button)
If Toolbar1.Buttons(Button.Index).Image = 1 Then
Toolbar1.Buttons(Button.Index).Image = 2
Else
Toolbar1.Buttons(Button.Index).Image = 1
End If
End Sub
