Picture box
A PictureBox control can be used to display a static image file on a form. Alternatively, you can use a PictureBox control as a drawing surface.
A PictureBox control will mantain a loaded image's aspect ratio if resized by the corner handles.
You can draw directly onto a PictureBox's surface using QB64's drawing commands:
