That just makes it sound like the picture is large enough that when you set the ImageLayout to none (or the default Tile), then all you're seeing is the upper left corner of the image which looks like it didn't show up because it must be a solid color, or could be transparent.
If the ImageLayout is none, or Tile, the image should be its full size, with the upper left corner located at the upper left corner of the client area of the picturebox.

Of course, that only explains what you're seeing in post #9, not what you've reported seeing in posts # 1 to 7.
