The PictureBox control can handle transparent images. Are you having problems with something inparticular?

Im using two pictureboxes

the image on the picture box has a transparent background, but when I move the control over the other picturebox I cannot see the both images at the same time.

I change the property "backcolor" in  both picturebox but I still cannot see both images one over the other
What does it mean to be "Always On"?

Rather than use two ImageBox controls, have you considered setting one image to the Image property and the other to the BackgroundImage property of one PictureBox?

the bottom picturebox has the backgorundimage property configured and the top picturebox has just the backcolor property to transparent

That's not what was suggested by kaufmed. What he suggested was to use one picture box, and set both it's Image and BackgroundImage properties to the relevant images.

Can you post the actual images you are using so I can check myself?

You can draw the images with transparency to a new image, then set the image to the PictureBox.
The PNG from file will retain its transparent color using DrawImage().  The bitmap can use a transparent color if you specify the color using MakeTransparent().
Dim FinalImage As Bitmap
		FinalImage = New Bitmap(PictureBox1.ClientSize.Width, PictureBox1.ClientSize.Height)

		Dim g As Graphics = Graphics.FromImage(FinalImage)

		'Load a PNG from file
		Dim image1 As Image = Image.FromFile("c:\rgb8_t_bk.png")
		'Load a resource BMP
		Dim image2 As Bitmap = System.Drawing.Image.FromHbitmap(My.Resources.ABitmap.GetHbitmap())

		g.DrawImage(image1, 0, 0)
		g.DrawImage(image2, 10, 10)

		PictureBox1.Image = FinalImage
