 The parameters are the path/filename of the image file, and the required position and size of the displayed image (measured in pixels from the top left-hand corner of the output window's client area).\\ \\  This code will also display **BMP**, **GIF** and **JPEG** images, and may do so with a better quality than the other methods. However it relies on the presence of the //GDI Plus// library so will work only on Windows XP (or later) or if you have specifically installed **GDIPLUS.DLL** on the target computer. Microsoft permits you to redistribute this file so you can include it with your program if necessary.
