|   /*
|     Read an image.
|   */
|   magick_wand=NewMagickWand();
|   status=MagickReadImage(magick_wand,argv[1]);
|   if (status == MagickFalse)
|     ThrowWandException(magick_wand);
|   /*
|     Turn the images into a thumbnail sequence.
|   */
|   MagickResetIterator(magick_wand);
|   while (MagickNextImage(magick_wand) != MagickFalse)
|     MagickResizeImage(magick_wand,106,80,LanczosFilter,1.0);
|   /*
|     Write the image then destroy it.
|   */
|   status=MagickWriteImages(magick_wand,argv[2],MagickTrue);
|   if (status == MagickFalse)
|     ThrowWandException(magick_wand);
| 

This still reads in ALL the images in the image stream into memory first
the processes each image.  Not appropriate for a 'image stream' that
could be for example a long video sequence.
