Just use the Form Paint method and draw every Picturebox on it  it allows transparency       private void frmGame Paint object sender  PaintEventArgs e                DoubleBuffered   true          for  int i   0  i  lt  Controls Count  i                if  Controls i  GetType      typeof PictureBox                                 var p   Controls i  as PictureBox                  p Visible   false                  e Graphics DrawImage p Image  p Left  p Top  p Width  p Height

I ve had a similar problem like this  You can not make Transparent picturebox easily such as picture that shown at top of this page  because  NET Framework and VS  NET objects are created by INHERITANCE   Use Parent Property    I solved this problem by RectangleShape and with the below code I removed background  if difference between PictureBox and RectangleShape is not important and doesn t matter  you can use RectangleShape easily   private void CreateBox int X  int Y  int ObjectType        ShapeContainer canvas   new ShapeContainer        RectangleShape box   new RectangleShape        box Parent   canvas      box Size   new System Drawing Size 100  90       box Location   new System Drawing Point X  Y       box Name    Box    ObjectType ToString        box BackColor   Color Transparent      box BorderColor   Color Transparent      box BackgroundImage   img Images ObjectType     Load from imageBox Or any resource     box BackgroundImageLayout   ImageLayout Stretch      box BorderWidth   0      canvas Controls Add box        For feature use

One way to do this is by changing the parent of the overlapping picture box to the PictureBox over which it is lapping  Since the Visual Studio designer doesn t allow you to add a PictureBox to a PictureBox  this will have to be done in your code  Form1 cs  and within the Intializing function   public Form1         InitializeComponent        pictureBox7 Controls Add pictureBox8       pictureBox8 Location   new Point 0  0       pictureBox8 BackColor   Color Transparent      Just change the picture box names to what ever you need  This should return

One fast solution is set image property for image1 and set backgroundimage property to imag2  the only inconvenience is that you have the two images inside the picture box  but you can change background properties to tile  streched  etc  Make sure that backcolor be transparent  Hope this helps
