Image coming out the wrong size...

Hello once again everyone. I'm just a newbie C# programmer with a problem...

Essentially through my code I have set the Image property of a picturebox to a .png file. I then allow the user to select an image and place it on top of this image, which I did utilizing the Graphics.DrawImage function.

Well...I was testing this out and everything works great, except certain images I draw come out larger then they actually are (they are proportionately stretched). This only happens to certain image files, and always for those image files. If I set the picturebox's image property to these images they are of correct size...

Any clues as to why this is happening?

Have you tried DrawImageUnscaled()?

Can you post your code so we can have a look?

I replicated the problem in a new project to make it easier to tackle...
All I did was place a picturebox on the form, and set it's image property to the desired image.

I then coded the picturebox click event as such:

Code:

---

private void pictureBox1_Click(object sender, System.EventArgs e)
{
  Graphics g = pictureBox1.CreateGraphics();
  g.DrawImageUnscaled(pictureBox1.Image, 20, 20);
}

---

Here is the image file I used as well..

Hopefully this problem is not only on my end.
