Watermark Picturebox

Draw directly on the form in the Paint event handler. Instead of setting PictureBox.Image property, use Graphics.DrawImage method.

If I draw it directly to a location, the next time the form is resized will I have multiple overlapping image?

If you want to draw background image, use the following code:

        Bitmap bmp;

        private void Form1_Load(object sender, EventArgs e)
        {
            bmp = new Bitmap("C:\\sample.bmp");        // replace this with your own bitmap

            this.SetStyle(
                ControlStyles.DoubleBuffer |
                ControlStyles.UserPaint |
                ControlStyles.AllPaintingInWmPaint |
                ControlStyles.ResizeRedraw,
                true);

            this.UpdateStyles();
        }

        private void Form1_Paint(object sender, PaintEventArgs e)
        {
            e.Graphics.DrawImage(bmp, this.ClientRectangle);
        }

When form is resized, image is redrawn completely covering all client area.

Alex, my image is only 200x200.  the clientrectangle parameter, is it possible for the image to be painted anchored to the bottom right hand corner?

I tried your code.  The image is stretched to the size of the form.  I need the image to remain in its original size but anchored to the bottom right hand corner

Try last post.

Alex, the image is now in the right place but the controls over the image still covers the image and does not show transparently.

I will increase the points.  thanks

The other controls are labels that I placed inside of a panel container.  This is the control I need to show through the watermark image.

What controls? I don't think that there is universal solution for all controls. For example, it is possible to make label transparent setting it's BackColor property to Transparent in the Form Designer of in the code:

this.label1.BackColor = System.Drawing.Color.Transparent;

Search information about every specific control type.

thanks, I got it work.
