Sample Visual Basic Procedure
Sub MakeTransparent

With ActiveWindow.Selection.ShapeRange .PictureFormat.TransparentBackground = msoTrue

' If you want to make a different color transparent, change the RGB ' values in the next line of code. For example, if you want to make ' black the transparent color, change: '     '   RGB(255, 255, 255) '     ' to      ' '  RGB(0, 0, 0) '        .PictureFormat.TransparencyColor = RGB(255, 255, 255) .Fill.Visible = msoFalse End With End Sub
