Neither are possible. There are a few different layout options for the BackgroundImage but you cannot specify a location. As for transparent controls, Windows表格 doesn't support genuine transparency and just fakes it by having a child control effectively display its parent as its own background. The only way a PictureBox can show through another PictureBox is if one is the parent of the other. That is possible, although you have to do it in code, as you cannot add children to a PictureBox in the designer. It also means that the child cannot be displayed beyond the bounds of the parent. If that's a problem, you may be able to get around that by having another PictureBox that is not a child that occupies the same area on the screen as the child, so you can see a transparent one inside the other PictureBox and still see on in the right place outside too.
