I started off with a VERY simple form and added a picturebox item to it. The code I was following used a procedure in the Form1.vb to override the transparent color of the image:

Code:
        bmp.MakeTransparent(Color.Fuchsia)
bmp was defined in the Form's "Load" section.

Now things are different. I have more than 20 picturebox items now, each created in the Form1.Designer.vb code as follows:

Code:
        Me.Tile020.Image = CType(resources.GetObject("Tile020.Image"), System.Drawing.Image)
        Me.Tile020.Location = New System.Drawing.Point(922, 297)
        Me.Tile020.Name = "Tile020"
        Me.Tile020.Size = New System.Drawing.Size(64, 64)
        Me.Tile020.TabIndex = 3
        Me.Tile020.TabStop = False
The image is referenced from the resources. When I run the program, I'd like all these images to have their backgrounds transparent. None of these controls is currently referenced anywhere in the code at present.

What's the best way to get them to display transparently, other than recreating them as transparent .PNG's?
