Solved: Using design toolbox.
I'm using the following method to add a image
private void cobertura1vertente_Load(object sender, EventArgs e)
PictureBox pb1 = new PictureBox();
pb1.Image = Image.FromFile("C:/cobertura1vertente.png");
pb1.Location = new Point(3, 3);
pb1.Size = new Size(250, 250);
//doubt right below
I usually would add a image to a entire form, but now i want to add it to a specific groupbox, who lies inside a tab.
If the code is correct, my guess is that the location that i've set is relative to the whole form, and not to the groupBox, why would that happen?
