Introduction
This sample is an MFC application using the document/view architecture
that can load, display and print graphics files such as GIF, JPEG, BMP (bitmap),
ICO (icon), WMF (metafile) and EMF (Win32-enhanced metafile). It shows
- how to use the
OleLoadPicturePath() function and the IPicture interface
to load and display those graphics files.
(Look into the ImgViewerDoc.cpp, ImgViewerView.cpp and MainFrm.cpp files.)
- how to support more than one file extension per MFC document type.
(Look into the MulExtDocTmp.cpp, MulExtDocTmp.h and ImgViewer.cpp files.)

How To Load and Display Graphics Files w/LOADPIC.EXE
(Note that LOADPIC.EXE does not handle palettes. As a result, it
won't display a 256-color image correctly in 256-color mode. Also, it uses
the OleLoadPicture() function instead of the OleLoadPicturePath() function.)
