GetImage Icons are 16 colors not 256

I'm using the Command Bars to add Tabs to my MDI workspace and including Icons from the selected item in the TaskPanel control. I am using the CommandBars.Icons.GetImage(Control.IconId, 32) to get the icon from the command bars and passing that through a subroutine

Function Add2(tClass As String, img As ImageManagerIcon) As Boolean

- in this routine I am setting the child MDI form Icon using the img that was passed from the commandbars

Set frmP.Icon = img.CreatePicture(xtpImageNormal)

the image shows but for some reason the image is only 16 colors instead of 256 - is there anything I should be doing differently

Thanks
